![]() The same information as the coding strand of DNA,Īs the other stand of DNA, because these nucleotides right over here, this nucleotide is going But if you think about the information that that RNA is actually going to encode, well it's gonna contain We could call the side that it is interacting with, you can call that the template strand because that side of the DNA is acting as the templateįor forming that RNA. I guess you could say, or coding complementary So as you can see here, when it does this, it's only encoding one side of. Notice this arrow here, we're extending it on the So it encodes from the five prime to the three prime direction. It does that the same way that when we studied DNA polymerase, it does it in only one direction. Not only it separates the strand and then it's actuallyĪble to code for the RNA. The helicase and whatever else, but this RNA polymerase complex It separates the strands, and it's pretty interesting, because when we went inĭeep into replication, you saw all of these actors, That's how the RNA polymerase knows to attach right over there. ![]() But in general, if you've got a gene, you're gonna have a promoter. Sometimes you might haveĪ promoter associated with a collection of genes as well. And every gene is going to have a promoter associated with it, especially if we're talkingĪbout eukaryotic cells. Is it attaches to a sequence of the DNA known as a promoter. Sequence that will become a nucleotide sequence, that Not the DNA or the mRNA here is going to be RNA polymerase. The protein coding gene inside of the DNA, right over here, and the primary actor that's So right over here, we are going to start with Talking about a eukaryotic cell what type of processing So now that we have that overview, let's dig a little bit deeper into this and understand the different actors and understand if we're Processed to turn into what we would call mRNA, which then can leave the nucleus to be translated into a protein. We would call pre-mRNA, let me write that down, pre-mRNA, which is depicted right over there, and then it needs to be In eukaryotic cells, and we're going to get into a little bit more depth in this video, the transcription, the DNA to mRNA, that happens inside of the nucleus. You start with that DNA, that protein coding gene in the DNA, and from that you code the messenger RNA, you see that in that purpleĬolor right over here, and then that messenger RNA can be involved with the ribosome, and that's the translation process to actually produce the polypeptide, to produce the protein. ![]() You have the DNA just floatingĪround in the cytosol, and so the transcription takes place. So this first step is the transcription, the DNA to messenger RNA, and then in a future video we'll dig a little bitĭeeper into translation. So transcription we are going from DNA to messenger RNA, and we're gonna, in this video, focus on genes that code for proteins. ![]() Take the information encoded in the gene in DNA and encode essentially that same information in mRNA. Rewrite some information in another form. Language just means to rewrite something or to And just as a bit of a review, we touch on it on the video on replication, transcriptionĪnd translation. Going to do in this video is a little bit of a deepĭive on transcription.
