• A. Uracil, thymine, cytosine, and guanine
• B. Adenine, thymine, cytosine, and guanine

• D. Adenine, uracil, cytosine, and guanine

Answer: (D)

Verified step by step guidance

1. Recall that RNA (ribonucleic acid) is a nucleic acid similar to DNA but differs in some key components, including the nitrogenous bases it contains.
2. List the four nitrogenous bases found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
3. Understand that in RNA, thymine (T) is replaced by uracil (U), so the bases are adenine (A), uracil (U), cytosine (C), and guanine (G).
4. Compare the given options to identify which set contains adenine, uracil, cytosine, and guanine, matching the RNA bases.
5. Conclude that the correct set of nitrogenous bases found in RNA is adenine, uracil, cytosine, and guanine.
