Question

In some circumstances, one mRNA transcript can lead to the translation of more than one protein.

(a) True

(b) False

I had been asked this question during an interview.

My question is from Genome Annotation in chapter Genome Mapping, Assembly and Comparison of Bioinformatics

Answer 1

The correct answer is:

(a) True

In some circumstances, one mRNA transcript can lead to the translation of more than one protein. This phenomenon is known as alternative splicing, where different combinations of exons are joined together to produce multiple mRNA variants from a single gene. Each of these variants can then be translated into distinct proteins, potentially with different functions. This process is a key mechanism of gene regulation and contributes to protein diversity in eukaryotic organisms.
