Question

Given below is the DNA coding sequence. Its complementary strand would read as:
5’ – GTATTACG – 3’

• A. 5’ – CUTUUTGC – 3’
• B. 3’ – CATAATGC – 5’
• C. 3’ – CUTUUTGC – 5’
• D. 5’ – CTUTTUGC – 3’

Answer 1

The Correct Option is B

The complementary strand of DNA is formed by pairing A with T and G with C. Thus, the sequence 5’ – GTATTACG – 3’ pairs with 3’ – CATAATGC – 5’.
