Question

The function(s) of the 5' methyl-G cap on mRNA is(are): (check all that apply)

Select one or more: a. Bind eukaryotic initiation factor 4G (eIF4G)

b. Recruit the large subunit of the ribosome to the 5' end of the mRNA

c. Prevent the degradation of the mRNA by 5' exoribonucleases

d. Ensure that only mRNAs with intact 3' ends are translated.

e. Recruit the small subunit of the ribosome to the 5' end of the mRNA

f. Invoke nonsense mediated decay of the mRNA

g. Bind RNA polymerase II initiation factors to start transcription

h. None of the other choices.

I get 0.50 out of 1 points when I put A C D E F and G

It is because also included wrong choices

The correct ones are

a.Bind eukaryotic initiation factor 4G (eIF4G)

c. Prevent the degradation of the mRNA by 5' exoribonucleases

e. Recruit the small subunit of the ribosome to the 5' end of the mRNA

b is wrong because it binding takes place with small subunit, d is wrong because that is done by Poly AA, f and g are as well wrong.
