Question

Which is common in both DNA and RNA?

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

Answer 1

The correct option is B

Adenine, guanine, cytosine

The correct option is B.

The explanation for the correct option:

1. Adenine, guanine, cytosine, uracil, and thymine are referred to as nitrogen bases present in genetic material.
2. In DNA, Adenine, Guanine, Cytosine, and Thymine are observed.
3. Whereas in RNA, Adenine, Guanine, Cytosine, and Uracil are observed.
4. In RNA, Thymine is replaced by Uracil.
5. Hence, Adenine, Guanine, and Cytosine are common to both DNA and RNA.

Final answer: Adenine, guanine, and cytosine are common in both DNA as well RNA.
