Question

Which nitrogenous bases are found in RNA molecules?

Options

• Adenine, guanine, cytosine, and uracil

• Adenine, guanine, cytosine, and thymine

• Cytosine, thymine, guanine, and uracil

• Adenine, thymine, guanine, and uracil

Answer 1

The four nitrogenous bases present in RNA are adenine (A), guanine (G), cytosine (C), and uracil (U). Uracil is unique to RNA and replaces thymine, which is found in DNA instead.
