Regulation after transcription (article) Khan Academy
WebTranscription is when we take the information encoded in the gene in DNA and encode essentially that same information in mRNA. So transcription we are going from DNA to messenger RNA, and we're gonna, in this video, focus on genes that code for proteins. So this first step is the transcription, the DNA to messenger RNA, and then in a future ... WebIn the nucleus, a pre-mRNA is produced through transcription of a region of DNA from a linear chromosome. This transcript must undergo processing (splicing and addition of 5' cap and poly-A tail) while it is still in the nucleus in order to become a mature mRNA. In contrast to introns, exons are the part of an mRNA transcript that actually contain … ravens win loss record

WebApr 11, 2024 · mRNA: teaching our cells to make their own vaccine Vaccines work by training our bodies to recognize invading viruses. Traditional vaccines perform this task by introducing a dead, inactive, or modified portion of a virus into our body so that our immune system can learn to recognize and fight this foreign invader. WebHow does pre-mRNA become mRNA? The pre-mRNA sequence is composed of regions called exons and introns in an interleaved manner. Only exons are used for protein coding so, on the splicing stage, introns are removed from the sequence and the exons are merged into a new chain, the mature mRNA. WebThe precursor mRNA or pre-mRNA is the primary transcript in the transcription process. It has both exons (coding sequence) and introns (non-coding sequence). Initially, it is produced from a DNA sequence inside the nucleus by transcription. It undergoes many processing stages before being converted into mRNA or mature messenger RNA. ravens win or lose
