The rat a- tropomyosin (a- Tm) gene produces nine different mature mRNA proteins from a single gene using which three "alternative" mechanisms?
A) 5' cap, branch points, polyadenylation
B) 5' cap, self- splicing, polyadenylation
C) splicing, start codon, stop codon
D) promoters, start codon, poly(A) signal sequences
E) splicing, promoters, and polyadenylation

Question

Quizplus · Accepted Answer

The rat α-tropomyosin gene produces nine different mature mRNA proteins from a single gene through alternative splicing, usage of different promoters, and alternative polyadenylation sites. These mechanisms allow for the generation of diverse protein isoforms from the same gene, contributing to the complexity of protein functions in cells.
