WebbThe eukaryotic pre-mRNA undergoes extensive processing before it is ready to be translated. Eukaryotic protein-coding sequences are not continuous, as they are in prokaryotes. The coding sequences (exons) are interrupted by noncoding introns, which must be removed to make a translatable mRNA. WebbThe three most important steps of pre-mRNA processing are the addition of stabilizing and signaling factors at the 5′ and 3′ ends of the molecule, and the removal of the introns ( (Figure) ). In rare cases, the mRNA transcript can be “edited” after it is transcribed. Figure 1. Eukaryotic mRNA contains introns that must be spliced out. black striped water snake https://jeffstealey.com

WebbRNA processing is the term collectively used to describe the sequence of events through which the primary transcript from a gene acquires its mature form. Very soon after synthesis by RNA polymerase II begins, pre-messenger RNAs transcribed from eukaryotic nuclear protein-coding genes acquire a 5׳ cap structure. Webb7 maj 2024 · In Eukaryotes, the transcription is followed by messenger RNA processing, where the pre-mRNA is processed to form mature m-RNA. The mature m-RNA not only become functional but also increases the half life time of m-RNA. In m-RNA processing, the pre-mRNA undergoes capping at 5’end, splicing and polyadenylation at 3’end.
