Question
Which of the Pair is Common among both DNA and RNA ?
The correct answer is
Adenine and Guanine
DNA and RNA Common Base Pair Identification
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are crucial nucleic acids. They both carry genetic information using a sequence of nitrogenous bases.
Nitrogenous Bases in DNA and RNA
- DNA Bases: Adenine (A), Guanine (G), Cytosine (C), and Thymine (T).
- RNA Bases: Adenine (A), Guanine (G), Cytosine (C), and Uracil (U).
Identifying Common Bases
Comparing the bases, we find that Adenine (A), Guanine (G), and Cytosine (C) are present in both DNA and RNA. Thymine (T) is unique to DNA, while Uracil (U) is unique to RNA.
Common Pair in DNA and RNA
The question asks for a common *pair*. Among the bases present in both DNA and RNA (A, G, C), the pair Adenine (A) and Guanine (G) are consistently found in both types of nucleic acids. Both A and G are classified as purines.
Therefore, the common pair is Adenine and Guanine.
