Correct Answer » B:C Explanation |

Ans. B & C
51 capping & poly A-tail addition are the post-transcriptional modification found only in eukaryotes, as in prokaryotes, primary transcript of mRNA is functional.
Thus it does not require post-transcriptional modification.
Binding to promoter region is a common step in both.
Reverse transcriptase requires this double-stranded segment as a primer to start its operation.
