Question

Which of the following would not prevent an mRNA from being transported to the rough endoplasmic

reticulum in the cytoplasm?
Group of answer choices

The ends of the mRNA were not modified.

The mRNA was not correctly spliced

The mRNA was not bound by a ribosome.

The mRNA is for a secreted protein.

Answer 1

The correct answer is mRNA is not bound by a ribosome.

Step-by-step explanation:

mRNA or messenger RNA is being modied for its transport from nucleus to the cytoplasm.The modifications are listed below

1 5" capping

2 3" tailing

3 splicing

If one these three events does not occur in newly formed mRNA or primary mRNA transcript then the mRNA will be prevented to be transported from nucleus to the cytoplasm.

But if the mRNA is not bound to the ribosome then this wil not not prevent mRNA to be transported into the cytoplasm because the binding of ribosome to mRNA occur after the mRNA has reached the cytoplasm.
