Question

The process by which a single gene can code for multiple proteins is called ___________

(a) transcription

(b) transformation

(c) alternative splicing

(d) sequencing

This question was addressed to me in an internship interview.

Asked question is from Genome Sequencing in chapter Nature of Genome of Cell Biology

Answer 1

The correct answer is:

(c) alternative splicing

Explanation:

Alternative splicing is a process during gene expression that allows a single gene to code for multiple proteins. It occurs when the exons of a gene are joined in different combinations during the splicing of the pre-mRNA transcript. This enables a single gene to produce multiple protein variants, increasing the diversity of proteins that can be produced from a single gene.
