What is the correct complimentary strand for the following DNA? ATCGAG
A
TACGAG
B
ATCGAG
C
TAGCTG
D
TAGCTC
Explanation: 

Detailed explanation-1: -The correct option is C The complementary DNA strand of the sequence ATGC will be TACG. The complementary base pairing in DNA is as per the Chargaff’s rules.

Detailed explanation-2: -noun Biochemistry. either of the two chains that make up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases. a section of one nucleic acid chain that is bonded to another by a sequence of base pairs.

Detailed explanation-3: -Solution : (c) Adenine always pairs with thymine and cytosine always pairs with guanine. Thus, sequence of bases on complementary strand would be TACGTACGT.
