General Genetics/Polyadenylation

Polyadenylation occurs in Eukaryotes to prevent RNA trasncript degradation. A number of enzymes are involved, which add hundreds to thousands of adenines to the 3' end of an mRNA transcript. Many of these adenines will be lost before translation - but enough are added to prevent degradation of the script prior to translation.
