How can one primary mRNA result in several polypeptrides with differnt amino acid sequences?
A)Alternative splicing of exons and introns.
B)Post-translational modification such as phosphorylation.
C)Pre-translational modification such as phosphorylation.
D)Modification of the mature mRNA by phosphorylation
