Which set lists the four nitrogenous bases found in RNA?

• A. Adenine, uracil, thymine, and cytosine
• B. Adenine, thymine, cytosine, and guanine
• C. Adenine, uracil, cytosine, and guanine
• D. Uracil, thymine, cytosine, and guanine

Answer: (C)

Verified step by step guidance

1. Recall that nucleic acids DNA and RNA are composed of nitrogenous bases, sugars, and phosphate groups.
2. Identify the four nitrogenous bases found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
3. Understand that RNA differs from DNA in one key base: RNA contains uracil (U) instead of thymine (T).
4. Therefore, the four nitrogenous bases in RNA are adenine (A), uracil (U), cytosine (C), and guanine (G).
5. Use this knowledge to select the correct set of bases for RNA, which excludes thymine and includes uracil.
