An mRNA sequence is 5'-CAGUUACGA...UAAGC-3' ([…] denotes intervening sequences).What is the sequence of the template strand of DNA?
A) 5'-CAGUUACGA...UAAGC-3'
B) 5'-CAGTTACGA...TAAGC-3'
C) 3'-CAGUUACGA...UAAGC-5'
D) 3'-GTCAATGCT...ATTCG-5'
E) 5'-GTCAATGCT...ATTCG-3'

Question

Quizplus · Accepted Answer

The template strand of DNA is complementary and antiparallel to the mRNA sequence. Therefore, the mRNA sequence 5'-CAGUUACGA...UAAGC-3' corresponds to a DNA template strand of 3'-GTCAATGCT...ATTCG-5', which is option D.
