Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If one series of bases reads:TTGACTAGG, then the complementary set of bases would read:
A
TTGACTAGG
B
AACTGATCC
C
AATCGAACTT
D
AAGTCATCC
Explanation: 

Detailed explanation-1: -The bases are paired by This is called complementary base pairs. Thus one strand of DNA is complementary to the other strand (opposite/matching).

Detailed explanation-2: -Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.

Detailed explanation-3: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.
