Alternative splicing may be considered a mechanism of gene regulation because it:

Question

Quizplus · Accepted Answer

Alternative splicing allows a single gene to encode multiple protein products by selectively including or excluding exons from the mRNA during processing. This gives the cell greater flexibility in regulating gene expression and ultimately protein function. The other choices are not accurate - A) DNA rearrangements generally refer to larger-scale changes like deletions, insertions, or translocations, which are not directly related to splicing; B) RNA editing is a separate process that can occur in addition to splicing, but it does not depend on splicing to occur; D) While splicing errors can be mutagenic if they result in disruptions to the reading frame or production of truncated proteins, the act of splicing itself is not mutagenic.
