An MRNA Molecule Has a Cap Attached to Its 5

Question

An mRNA molecule has a cap attached to its 5' end and a poly-A tail attached to its 3' end.

Accepted Answer

This is true. In eukaryotic mRNA, a 7-methylguanosine (m7G) cap is added to the 5' end and a poly-A tail is added to the 3' end. These modifications help stabilize the mRNA molecule and facilitate translation.
