Which of the following structures represents a thymine deoxyribonucleotide?

Step-by-step solution

A nucleotide is composed of three components: a nitrogenous base, a pentose sugar, and a phosphate group. For a thymine deoxyribonucleotide: 1. The nitrogenous base must be thymine, which is a pyrimidine derivative (5-methyluracil) containing a six-membered ring with two carbonyl groups and a methyl group. 2. The sugar must be 2'-deoxyribose, which lacks a hydroxyl group at the 2' position. 3. A phosphate group must be attached to the 5' carbon of the sugar.
