Alternative RNA Splicing

Question

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

Accepted Answer

Alternative RNA splicing is a process in which different combinations of exons within a single gene are spliced together, resulting in the production of different mRNA variants. These mRNA variants can then be translated into proteins with different sizes and functions. Thus, option B is the correct choice as it correctly describes the outcome of alternative RNA splicing.
