Answer:
<h2>
AAUAA deletion- (B
)
</h2><h2>
</h2><h2>
Poly(A) tail deletion- (C)
</h2><h2>
</h2><h2>
5' cap deletion- (A)
</h2>
Explanation:
(A) introns are not removed from the pre-mRNA due to 5' deletion;
(B) the pre-mRNA is not cleaved at the cleavage site due to AAUAA deletion
(C) the mRNA is not transported to the cytoplasm due to poly A tail deletion;
AAUAA deletion: if we delete the AAUAA sequence then there is the change of sequence of pre- mRNA that the pre-mRNA is not cleaved at the cleavage site
.
Poly(A) tail deletion: Poly(A) tail is the long tail of Adenine in the 3' end of mRNA, after the deletion of Poly(A) tail, it affects the transport of mRNA from the nucleus to the cytoplasm and the mRNA is not transported to the cytoplasm if tail is deleted.
5' cap deletion; the effect of 5' cap deletion is that introns are not removed from the pre-mRNA. The process of intron removing and exon joining is called RNA splicing.
It seems that you have missed the necessary details and options for us to answer this question so I had to look for it. Anyway, based on the given description above, the molecule which is considered the "gas" that powers a cell's "engine" is called the Adenosine Triphosphate or ATP. Hope this helps.
