Why are the number of proteins in the eukaryotic proteome so much greater than the number of eukaryotic genes?
What will be an ideal response?
Eukaryotic translation is characterized by transcript processing, where, in many cases, exons are differentially spliced to yield different polypeptide products. In addition, many functional proteins have quaternary structure, the subunits of which are provided by different genes. The number of possible proteins thus greatly exceeds the base number of genes in the genome.
