Which mechanism of posttranscriptional regulation of gene expression can produce several different proteins from a single gene?

Question

Quizplus · Accepted Answer

Alternative splicing is a mechanism of posttranscriptional regulation that generates different protein isoforms from a single gene. This is achieved by different patterns of splicing of the pre-mRNA, resulting in various combinations of exons being included or excluded from the final mRNA transcript. This process can produce different protein isoforms with distinct structural, functional, or regulatory properties, contributing to the complexity and diversity of the proteome. The other choices, such as miRNA binding, protein degradation, protein phosphorylation, or translation regulation, can also regulate gene expression posttranscriptionally but do not directly produce different protein isoforms.
