the following is NOT a function of
these?
A. allows the strand to leave the nucleus
B. helps the strand attach to a ribosome to be
translated
C. signals that introns need to be spliced out
D. protects the strand from enzymes
Answer: The answer is C
Explanation: The answer is signals that introns need to be sliced out, I got it right!
C. signals that introns need to be spliced out. The 5' cap and the poly A tail of an RNA molecule serve to allow the molecule to exit the nucleus, attach to a ribosome, and protect from degradation. They do not signal for introns to be spliced out.
The RNA molecule has a 5' cap and a Poly A tail at the 3' end. These modifications play a few key roles in the functionality of the RNA molecule but the statement 'signals that introns need to be spliced out' (option C) is NOT one of the functions of these modifications.
The 5' cap allows the RNA to exit the nucleus and attach to a ribosome, while the poly-A tail helps stabilize the RNA, aids in the exit from the nucleus, promotes translation, and protects the RNA strand from enzymes that degrade RNA from the 3' end. Neither of these modifications signal for introns to be spliced out, that is primarily the function of spliceosome complex which recognize specific site sequences within the RNA.
