In Eukaryotes,primary MRNA Transcripts are Extensively Processed,which Include(s)

Question

In eukaryotes,primary mRNA transcripts are extensively processed,which include(s):
A)modification of the 5′ end.
B)modification of the 3′ end.
C)removal of introns by splicing.
D)None of the answer options are correct.
E)modification of either end and removal of introns by splicing.

Accepted Answer

Primary mRNA transcripts in eukaryotes require extensive processing, including modifications to the 5' and 3' ends and the removal of introns through splicing. Therefore, the best choice is E, which includes both modifications to either end and intron removal through splicing. The other options, A, B, and C, do not cover all the necessary processing steps. Option D, None of the answer options are correct, is incorrect as all of the options have some validity, but E is the most complete.
