Question

A region of a coding DNA strand has the following nucleotide sequence:

-ATGC-
What shall be the nucleotide sequence in (i) sister DNA segment it replicates, and (ii) m-RNA polynucleotide it transcribes?

Answer 1

Dear Student


(i). The nucleotide sequence in a sister DNA sequence it replicates will be TACG.

(ii). The nucleotide sequence in mRNA polynucleotide will be AUGC. This is because the the sequence of mRNA is same as coding strand of DNA but thymine (T) is replaced by uracil (U) in mRNA.
