Architecture of eukaryotic mRNA 3′-end processing machinery

Webof pre-mRNAs are both necessary and sufficient for 3 - end formation. Several features of the chemistry of the 3 processing of histone and polyadenylated mRNAs also appear to be shared (Dominski and Marzluff 1999). Iden-tical cleavage products, a 3 hydroxyl and a 5 phosphate, are generated by a mechanism that does not require ATP hydrolysis. WebEukaryotic pre-mRNA processing. DNA gene is transcribed to pre-mRNA, which is then processed to form a mature mRNA, and then lastly translated by a ribosome to a protein ...

Eukaryotic RNA Processing – Principles of Biology

WebDec 30, 2009 · After cleavage, most pre-mRNAs, with the exception of histone replication-dependent transcripts, acquire a polyadenylated tail. 3′ end processing is a nuclear co-transcriptional process that promotes transport of mRNAs from the nucleus to the cytoplasm and affects the stability and the translation of mRNAs. WebPre-mRNA has to undergo at least two, and usually 3, processing steps before they can be exported to the cytoplasm as mature mRNA. These are, in order: The 5′ end of the pre-mRNA is modified by the covalent attachment of a 7-methylG nucleotide, called the 5′-cap. The 5′ cap is required for eukaryotic ribosomes to initiate translation. WebThe eukaryotic pre-mRNA undergoes extensive processing before it is ready to be translated.

WebEukaryotic pre-mRNAs are modified with a 5' methylguanosine cap and a poly-A tail. These structures protect the mature mRNA from degradation and help export it from the nucleus. Pre-mRNAs also undergo splicing, in which introns are removed and exons are reconnected with single-nucleotide accuracy.
