What modification often occurs to the GTP cap on mRNA?
A)Amination.
B)Deamination.
C)Methylation.
D)Demethylation.

Question

Quizplus · Accepted Answer

The modification that often occurs to the GTP cap on mRNA is methylation. This modification involves the addition of a methyl group to the guanine nucleotide at the 7th position, and it is important for the stability and processing of the mRNA molecule. Methylation of the GTP cap is also involved in the regulation of gene expression and can affect the efficiency of translation. Amination and deamination involve the addition or removal of amino groups, respectively, and are not typically associated with GTP cap modification. Demethylation involves the removal of methyl groups and is not consistent with the known modification of the GTP cap on mRNA.
