Paul Andersen explains the central dogma of biology. He explains how genes in the DNA are converted to mRNA through the process of transcription. He then explains how ribosomes use this message to convert the mRNA to a functioning protein. He also shows you how to decode a gene by converting the DNA to complementary mRNA and then to the specific amino acids in a protein.

Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript. Transcription proceeds in the following general steps: RNA polymerase, together with one or more general transcription factors, binds to promoter DNA. RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. This is done by breaking the hydrogen bonds between complementary DNA nucleotides. RNA polymerase adds RNA nucleotides (which are complementary to the nucleotides of one DNA strand). RNA sugar-phosphate backbone forms with assistance from RNA polymerase to form an RNA strand. Hydrogen bonds of the RNA–DNA helix break, freeing the newly synthesized RNA strand. If the cell has a nucleus, the RNA may be further processed. This may include polyadenylation, capping, and splicing. The RNA may remain in the nucleus or exit to the cytoplasm through the nuclear pore complex. Transcription of a gene takes place in three stages: initiation, elongation, and termination. Here, we will briefly see how these steps happen in bacteria. You can learn more about the details of each stage (and about how eukaryotic transcription is different) in the stages of transcription article. Initiation. RNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription. Elongation. One strand of DNA, the template strand, acts as a template for RNA polymerase. As it "reads" this template one base at a time, the polymerase builds an RNA molecule out of complementary nucleotides, making a chain that grows from 5' to 3'. The RNA transcript carries the same information as the non-template (coding) strand of DNA, but it contains the base uracil (U) instead of thymine (T). Termination. Sequences called terminators signal that the RNA transcript is complete. Once they are transcribed, they cause the transcript to be released from the RNA polymerase Eukaryotic pre-mRNAs must have their ends modified, by addition of a 5' cap (at the beginning) and 3' poly-A tail (at the end). Many eukaryotic pre-mRNAs undergo splicing. In this process, parts of the pre-mRNA (called introns) are chopped out, and the remaining pieces (called exons) are stuck back together.

Transcription and Translation - Protein Synthesis From DNA - Biology
 
10:55
This biology video tutorial provides a basic introduction into transcription and translation which explains protein synthesis starting from DNA. Transcription is the process where DNA is used to create mRNA. RNA polymerase constructs DNA using the template strand or antisense strand. The other strand is called the noncoding strand or nontemplate strand. pre-mRNA is actually created first through 3 processes - initiation, elongation, and termination. After which, pre-mRNA undergoes RNA splicing where the introns are removed and the exons remain. mRNA now leaves the nucleus and enters the cytosol where it finds a ribosome which is the site where proteins are made. The nucleotide sequence found in mRNA is broken into sets of 3 forming codons which matches the anticodons found in tRNA. The transfer RNA molecule brings the amino acids needed to make the growing polypeptide chain forming a protein. The ribosome has three sites - The E site or exit site, the P site or peptidyl site, and the A site or amino acyl site where most tRNA molecules enter.

Eukaryotic transcription part 1: introduction
 
14:02
For more information, log on to- http://shomusbiology.weebly.com/ Download the study materials here- http://shomusbiology.weebly.com/bio-materials.html Eukaryotic transcription is more complex than prokaryotic transcription. For instance, in eukaryotes the genetic material (DNA), and therefore transcription, is primarily localized to the nucleus, where it is separated from the cytoplasm (in which translation occurs) by the entaamoeboic nuclear membrane. DNA is also present in mitochondria in the cytoplasm and mitochondria utilize a specialized RNA polymerase for transcription. This allows for the temporal regulation of gene expression through the sequestration of the RNA in the nucleus, and allows for selective transport of RNAs to the cytoplasm, where the ribosomes reside. The basal eukaryotic transcription complex includes the RNA polymerase and additional proteins that are necessary for correct initiation and elongation. Among eukaryotes that regulate the transcription of individual genes, the core promoter of protein-encoding gene contains binding sites for the basal transcription complex and RNA polymerase II, and is normally within about 50 bases upstream of the transcription initiation site. Further transcriptional regulation is provided by upstream control elements (UCEs), usually present within about 200 bases upstream of the initiation site. The core promoter for Pol II sometimes contains a TATA box, the highly conserved DNA recognition sequence for the TATA box binding protein, TBP, whose binding initiates transcription complex assembly at the promoter. Some genes also have enhancer elements that can be thousands of bases upstream or downstream of the transcription initiation site. Combinations of these upstream control elements and enhancers regulate and amplify the formation of the basal transcription complex Source of the article published in description is Wikipedia.

We want students to go beyond our videos to explore the depth of the material. P.S. On our website, we emphasize that our videos contain science comics- not scientific illustrations. In real life, amoebas don't look like our characters. Our illustrated cell cartoons are definitely not to scale. Nitrogen and carbon don't tap dance. DNA is right-handed (but there are exceptions- worth a google) and doesn't have eyes...a face...or a top hat...

NDSU Virtual Cell Animations Project animation "Regulated Transcription". For more information please see http://vcell.ndsu.edu/animations. Gene expression is controlled in many different ways. When proteins from outside a cell signal for a specific gene to be transcribed, it is known as regulated transcription. This animation illustrates how a protein like insulin can trigger a regulated transcription event, in addition to setting off the signal pathway illustrated in our Insulin Signaling video.

Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (mRNA) by the enzyme RNA polymerase. Both RNA and DNA are nucleic acids, which use base pairs of nucleotides as a complementary language. The two can be converted back and forth from DNA to RNA by the action of the correct enzymes. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript. Transcription proceeds in the following general steps: One or more sigma factor protein binds to the RNA polymerase holoenzyme, allowing it to bind to promoter DNA. RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. This is done by breaking the hydrogen bonds between complementary DNA nucleotides. RNA polymerase adds matching RNA nucleotides to the complementary nucleotides of one DNA strand. RNA sugar-phosphate backbone forms with assistance from RNA polymerase to form an RNA strand. Hydrogen bonds of the untwisted RNA-DNA helix break, freeing the newly synthesized RNA strand. If the cell has a nucleus, the RNA may be further processed. This may include polyadenylation, capping, and splicing. The RNA may remain in the nucleus or exit to the cytoplasm through the nuclear pore complex. The stretch of DNA transcribed into an RNA molecule is called a transcription unit and encodes at least one gene. If the gene transcribed encodes a protein, messenger RNA (mRNA) will be transcribed; the mRNA will in turn serve as a template for the protein's synthesis through translation. Alternatively, the transcribed gene may encode for either non-coding RNA (such as microRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), or other enzymatic RNA molecules called ribozymes.[1] Overall, RNA helps synthesize, regulate, and process proteins; it therefore plays a fundamental role in performing functions within a cell.

Transcription in Eukaryotes | Biology Lecture 10
 
07:37
Transcription is the process of copying genetic information from one strand of DNA into RNA. Eukaryotic transcription takes place in the nucleus of the cell and proceeds in three sequential stages : Initiation, Elongation and Termination. Three different RNA polymerases are responsible for the transcription of the different RNAs. RNA polymerase I transcribes rRNA genes, RNA polymerase III transcribes tRNA, 5srRNA and snRNAs and RNA polymerase II transcribes all of the protein-coding genes. The Initiation of transcription involves the binding of several transcription factors along with RNA polymerase II to the promoter sequences. The mRNA is synthesized in 5' to 3' direction. When RNA polymerase II reaches the termination region of DNA, it gets cleaved from the RNA transcript and the RNA transcript{ pre-mRNA} undergoes post transcriptional modifications finally forming a mature mRNA.

What is RNA | Biology for All | FuseSchool
 
02:56
DNA is a type of nucleic acid. And in this video we are going to have a quick look at another type; RNA. We have both DNA and RNA in our bodies. We need them both! DNA is the blueprint; it contains all of the instructions for the cell to grow, function and replicate. The RNA carries out these instructions; it copies and transfers the genetic code from the DNA to ensure the relevant proteins are made. So just think of it as “DNA makes RNA make proteins”. Whereas DNA stands for deoxyribonucleic acid, RNA stands for ribonucleic acid. Whilst DNA is double stranded, RNA is single stranded. Like DNA, RNA is made up of a long chain of nucleotides. Each nucleotide consists of a ribose sugar, phosphate group and a nucleotide base. RNA has a sugar called ribose, whereas DNA has a sugar called deoxyribose. RNA has a base uracil, or U, whereas DNA has the base thymine or T. So in RNA C and G still pair, but now A and U pair. We need to know about RNA because we will see it when learning about protein synthesis. We will see two special types of RNA: messenger RNA which is known as mRNA. And transfer RNA which is known as tRNA. We will see the mRNA being synthesised inside the nucleus, copied from the DNA code. The tRNA is found in the cytoplasm. For many years, we just thought RNA was a DNA photocopier as mRNA, the protein builder as tRNA and found in ribosomes as rRNA. However, RNA can also act as enzymes to speed up chemical reactions. And in many viruses, they have RNA instead of DNA. The RNA carries the genetic code in these viruses. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.

Transcription initiation in prokaryotes | prokaryotic transcription lecture 2
 
22:42
Transcription initiation in prokaryotes – This lecture explains about the prokaryotic transcription initiation. The nucleotide pair within the DNA double helix that corresponds to the web page from which the first 5' mRNA nucleotide is transcribed is referred to as the +1 website online, or the initiation website. Nucleotides preceding the initiation site are given poor numbers and are exact upstream. Conversely, nucleotides following the initiation site are denoted with "+" numbering and are referred to as downstream nucleotides. A promoter is a DNA sequence onto which the transcription machinery binds and initiates transcription. Mostly, promoters exist upstream of the genes they regulate. The targeted sequence of a promoter is very important when you consider that it determines whether the corresponding gene is transcribed at all times, one of the crucial time, or sometimes. Although promoters differ among prokaryotic genomes, just a few elements are conserved. At the -10 and -35 regions upstream of the initiation website, there are two promoter consensus sequences, or areas which are an identical throughout all promoters and throughout various bacterial species. The -10 consensus sequence, called the -10 region, is TATAAT. The -35 sequence, TTGACA, is famous and certain through σ. Once this interaction is made, the subunits of the core enzyme bind to the website online. The A–T-rich -10 neighborhood facilitates unwinding of the DNA template; a few phosphodiester bonds are made. The transcription initiation section ends with the creation of abortive transcripts that are polymers of roughly 10 nucleotides which are made and released.
