Lecture Molecular biology (Fifth Edition): Chapter 15 - Robert F. Weaver

Chapter 15 - RNA Processing II: Capping and Polyadenylation. Besides splicing, eukaryotic cells perform several other kinds of processing on their RNAs. Messenger RNAs are subject to two kinds of processing, known as capping and polyadenylation. In capping, a special blocking nucleotide (a cap) is added to the 59-end of a pre-mRNA. In polyadenylation, a string of AMPs (poly[A]) is added to the 39-end of the pre-mRNA. These steps are essential for the proper function of mRNAs and will be topics in this chapter.
