Question

Alternative RNA splicing is a mechanism that?

1) increases the rate of transcription
2) allows the production of proteins of dramatically different sizes from a single mRNA
3) allows the production of proteins of dramatically different amino acid sequences from a single mRNA
4) B and C only
5) A, B, and C

Answer 1

Alternative RNA splicing allows the production of proteins with different sizes and amino acid sequences from a single mRNA.

Step-by-step explanation:

Alternative RNA splicing is a mechanism that allows different combinations of introns, and sometimes exons, to be removed from the primary transcript. This process generates different protein products from a single gene. Therefore, the correct answer to the question is option 4) B and C only, since alternative splicing enables the production of proteins with dramatically different sizes and amino acid sequences from a single mRNA.
