The complementary strand of DNA for the following single stranded DNA sequence: 5' - A - T - C- A - T - G - C-3' is:

Solution:

Correct Answer :- C

Explanation : In DNA, Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C).

Hence, on replication of DNA in M phase, complementary nucleotides for each base pair will be added as follows:

A - T

T - A

G - C

C - G

Since replication occurs in 5'-3' direction, so the complementary strand will be formed in 3'-5' direction.
