Question Detail
Question
In DNA, the purines are ; and the pyrimidines are : a. cytosine and thymine; adenine and guanine b. adenine and thymine; cytosine and guanine c. cytosine and guanine; adenine and thymine d. adenine and guanine; cytosine and thymine
Correct Answer
Option D is the correct answer.
Detailed Explanation
Purines are nitrogenous bases with a double-ring structure. In DNA, the purines are Adenine (A) and Guanine (G). Pyrimidines have a single-ring structure. In DNA, the pyrimidines are Cytosine (C) and Thymine (T).
