Which of the Following Allows More Than One Type of Protein

Question

Which of the following allows more than one type of protein to be produced from one gene?
A) control of mRNA stability
B) alternative forms of RNA splicing
C) control of the frequency of translation initiation
D) alternative forms of chromatin remodeling
E) all of the above

Accepted Answer

Alternative forms of RNA splicing allow for the production of multiple protein isoforms from a single gene by selectively splicing different exons together. The other choices do not directly involve altering the coding sequence of the mRNA and would not result in different protein products.
