WebThe 5′ UTR begins at the transcription start siteand ends one nucleotide(nt) before the initiation sequence(usually AUG) of the coding region. In prokaryotes, the length of the 5′ UTR tends to be 3–10 nucleotides long, while in eukaryotes it tends to be anywhere from 100 to several thousand nucleotides long.[3] Web1 hour ago · Orthopneumoviruses characteristically form membrane-less cytoplasmic inclusion bodies (IBs) wherein RNA replication and transcription occur. Herein, we report a strategy whereby the orthopneumoviruses sequester various components of the eiF4F Initiation Complex machinery into viral IBs to facilitate translation of their own mRNAs; …

WebPre-mRNA splicing is an essential mechanism for ensuring integrity of the transcriptome in eukaryotes. Therefore, splicing deficiency might cause a decrease in functional proteins and the production of nonfunctional, aberrant proteins. To prevent the production of such aberrant proteins, eukaryotic cells have several mRNA quality control mechanisms. In … WebAbstract. Polyadenylation [poly (A)] signals (PAS) are a defining feature of eukaryotic protein-coding genes. The central sequence motif AAUAAA was identified in the mid-1970s and subsequently shown to require flanking, auxiliary elements for both 3′-end cleavage and polyadenylation of premessenger RNA (pre-mRNA) as well as to promote ...
