BIOMOLECULES AND ENZYMES

Detailed explanation-1: -(c) Adenine always pairs with thymine and cytosine always pairs with guanine. Thus, sequence of bases on complementary strand would be TACGTACGT.

Detailed explanation-2: -DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together.

Detailed explanation-3: -In DNA, there are four different bases: adenine (A), guanine (G), cytosine (C) and thymine (T). Each base has its complementary base, which means in the double helical structure of DNA, A will have T as its complimentary and similarly G will have C.

Detailed explanation-4: -Replication relies on complementary base pairing, that is the principle explained by Chargaff’s rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
