There is a substantial difference between the number of genes and the number of proteins in many eukaryotic genomes, especially those of mammals. It is common for large eukaryotic genomes to express more proteins than there are genes in the genomes. There are three mechanisms that can produce alternative transcripts from single genes. Which mechanism, exhibited by the human CT/CGRP gene, involves post-translational processing of identical pre-mRNAs leading to different mature mRNAs?
