Ribonucleotides (rNTPs) and deoxyribonucleotides (dNTPs) are different for the following reason (s):

a. dNTPs are polymerized 5'-to-3', while rNTPs are polymerized 3'-to-5'.

b. dNTPs lack a hydroxyl group on the 2' carbon of their ribose sugar.

c. dNTPs are in the nucleus while rNTPs are found only in the cytoplasm.

d. rNTPs use thymine instead of uracil as a base.

b. dNTPs lack a hydroxyl group on the 2' carbon of their ribose sugar.

Explanation:

Ribonucleotides (rNTPs) and deoxyribonucleotides (dNTPs) are the monomers for RNA and DNA respectively. Both are the nucleotides with a pentose sugar, a nitrogenous base, and a phosphate unit. The Ribonucleotides (rNTPs) and deoxyribonucleotides (dNTPs) differ from each other with respect to pentose sugar. The ribonucleotides (rNTPs) have ribose sugar while deoxyribonucleotides (dNTPs) have deoxyribose sugar. The deoxyribose sugar of dNTPs lacks hydroxyl group at 2' carbon which is otherwise present in the ribose sugar.
