Answer: The nitrogenous bases are complementary to each other which means the complementary bases will bind with each other. Example: Adenine will bind with Thymine and Guanine will bind to Cytosine.
Explanation:
ACTGGAT→ TGACCTA
GCGTACA→ CGCATGT
CGGTTAA→ GCCAATT
AATGGCC→ TTACCGG
ATTGCGT→ TAACGCA
This is how the nitrogenous bases are paired in DNA(deoxyribonucleic acid) which makes one individual different from other.
