Which is not a feature of eukaryotic mRNA processing?
A)Addition of a 5'-5' triphosphate linkage to GTP.
B)Methylation of the terminal CCA triad.
C)Addition of a polyA tail to the 3' end.
D)Removal of intron sequences.

Question

Quizplus · Accepted Answer

Methylation of the terminal CCA triad is a feature of tRNA processing, not mRNA processing. The other options are all features of eukaryotic mRNA processing. Addition of a 5'-5' triphosphate linkage to GTP occurs during capping of the 5' end of mRNA, addition of a polyA tail occurs at the 3' end of mRNA, and removal of intron sequences occurs via splicing.
