Question

A correct example of a nucleotide is:

• A. adenosine monophosphate (AMP)
• B. RNA
• C. uridine
• D. DNA

Hint:

A nucleotide consists of a nitrogenous base, a sugar, and a phosphate group. A nucleoside lacks the phosphate group.

Answer 1

The Correct Option is A

A nucleotide consists of a nitrogenous base, a sugar molecule, and a phosphate group. Among the options, adenosine monophosphate (AMP) is a nucleotide, containing adenine (the nitrogenous base), ribose (the sugar), and a single phosphate group.

Step 1: Analyze the options.
- (A) AMP is a nucleotide, as it contains the three essential components.
- (B) RNA is a nucleic acid, not a single nucleotide.
- (C) Uridine is a nucleoside, not a nucleotide, as it lacks a phosphate group.
- (D) DNA is a type of nucleic acid, not a single nucleotide.

Final Answer: (A) adenosine monophosphate (AMP)
