Question

A combination of a ribose molecule, a thymine and a sugar molecule will form a

• A. Ribosome
• B. Nucleotide
• C. Nucleic acid
• D. ATP
• E. ADP

Answer 1

Answer: (B)

Nucleotide

Each nucleotide consists of a phosphate group, a nitrogenous base, and a pentose sugar molecule. Adenine, thymine, guanine, cytosine, and uracil are bases while ribose and deoxyribose are the pentose sugars. A combination of ribose, thymine and phosphate moiety forms a nucleotide.

So, the correct answer is option B.
