Question

Quizplus · Accepted Answer

Alternative splicing is the process where different combinations of exons within a single gene are spliced together to produce multiple different mRNA transcripts and protein isoforms. This is a major contributor to the production of a large number of proteins from a relatively small number of protein-coding genes in the human genome.
