Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the correct complimentary DNA strand for the following DNA molecule? ATC GAG
A
TAC GAG
B
ATC GAG
C
TAG CTC
Explanation: 

Detailed explanation-1: -Complementary Sequence: Since DNA has two strands, every DNA sequence has a complementary sequence running parallel. In the complementary sequence, Adenine (A) is always paired with Thymine (T), and Cytosine (C) is always paired with Guanine (G).

Detailed explanation-2: -The sequence of the mentioned DNA strand is 5’-ATCAGC-3’. So, the sequence of the complementary strand will be 3’-TAGTCG-5’.

Detailed explanation-3: -If one strand of DNA is CGGTAC, the corresponding strand would be: E. GCCATG. We can determine this due to the complementary base pairing that occurs in DNA: C base pairs with G, and A base pairs with T.
