Alternative RNA splicing ________.
A) is a mechanism for increasing the rate of transcription
B) can allow the production of proteins of different sizes and functions from a single mRNA
C) can allow the production of similar proteins from different genes
D) increases the rate of transcription
E) is due to the presence or absence of particular snRNPs

Question

Quizplus · Accepted Answer

Alternative RNA splicing refers to the process by which different combinations of exons from a single pre-mRNA molecule are selected and joined together, resulting in the production of different protein isoforms with distinct sizes and functions. It does not affect the rate of transcription or involve the presence or absence of snRNPs.
