Question
Chapter 12, Problem 10TY
Summary Introduction
Introduction:
Alternative splicing is also termed as differential splicing. This process is used to regulate gene expression and results in formation of different proteins from a single gene. In this process, exons are included or excluded from the processed mRNA translated from the given gene.
