BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Explanation: Adenine(A) pairs with thymine(T) and vice versa while guanine(G) pairs with cytosine(C) and vice versa. The bases are complementary, always appearing opposite to each other on the DNA double helix.

Detailed explanation-2: -Answer and Explanation: If a DNA strand has the sequence 5’-ATG-3’, the complementary messenger RNA (mRNA) sequence made using this DNA template would have the sequence 3’-UAC-5’.

Detailed explanation-3: -Complementary sequence: Nucleic acid sequence of bases that can form a double-stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C.

Detailed explanation-4: -In the complementary strand of DNA, the bases that bind to TAC are complimentary, thus they are ATG.

Detailed explanation-5: -(c) Adenine always pairs with thymine and cytosine always pairs with guanine. Thus, sequence of bases on complementary strand would be TACGTACGT.
