The pre-mRNA transcript of mammalian α-tropomyosin undergoes ____ to produce different mRNAs in smooth and striated muscles.
A) aminoacylation
B) alternative splicing
C) polyadenylation
D) degeneracy
E) exon shuffling

Question

Quizplus · Accepted Answer

Alternative splicing allows a single pre-mRNA transcript to be spliced in different ways to produce different mRNAs, leading to the production of different proteins in different tissues, such as smooth and striated muscles in the case of α-tropomyosin.
