Question

Choose the correct mRNA sequence for the given DNA sequence.

5'- AGTTCG- 3'

• A. 3'-TCUUGC-5'
• B. 5'-UCAACG-3'
• C. 5'-AGTTCG-3'
• D. 5'-TCAACG-3'
• E. 3'-UCAAGC-5'

Answer 1

The correct option is E 3'-UCAAGC-5'

• According to complementary base pairing, adenine makes two hydrogen bonds with thymine and guanine makes three hydrogen bonds with cytosine.
• RNA has uracil in place of thymine, so adenine pairs with uracil in RNA.
• So, the mRNA sequence of the DNA sequence 5'-AGTTCG-3' would be 3'-UCAAGC-5'

5'-AGTTCG-3'

3'-UCAAGC-5'

Thus, the correct answer is option E.
