Question:
What is the primary purpose of the poly(A) tail attached to a primary transcript before translation?
a) It signals the ribosome to terminate translation
b) It protects the transcript from degradation ✅
c) It gives the ribosome a site to begin translation
d) It signals the mRNA where to travel to be translated
e) It prevents polymerization with additional TTT nucleotides
✅ Correct Answer: B — It protects the transcript from degradation.
The poly(A) tail increases mRNA stability, aids in nuclear export, and enhances translation — a high-yield concept frequently tested on the DAT.
