Alternative splicing can:
A) be tissue-specific.
B) produce proteins with different functions from the same gene.
C) contribute to temporal control of gene expression.
D) produce mRNAs that are nonfunctional.
E) all of the above.

Question

Quizplus · Accepted Answer

Alternative splicing can lead to different isoforms of the same gene being expressed in different tissues, allowing for tissue-specific gene expression. These isoforms may have different functions or regulatory properties, contributing to functional diversity. Additionally, alternative splicing can be regulated in a temporal manner, allowing for dynamic control of gene expression during development and other processes. However, incorrect splicing events can sometimes result in nonfunctional or potentially harmful mRNA transcripts. Therefore, all of the listed choices are accurate explanations of the effects of alternative splicing.
