Give reason: The two strands of DNA molecule are complementary to each other but are not identical.

Description : Give reason: The two strands of DNA molecule are complementary to each other but are not identical.

Last Answer : The two strands of DNA are not identical because the nitrogenous bases are different in pairing. A purine base of one polynucleotide chain always pairs with a pyramidine base on the other. Adenine (A) pairs ... and Cytosine (C) pairs with Thymine (T). Hence the two strands of DNA are complementary.
