Question:
Which of the following are present in DNA?
Which of the following are present in DNA?
Show Hint
DNA is composed of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). A pairs with T, and C pairs with G in the double helix structure.
Updated On: Mar 13, 2025
- A, D
- A, C, D
- B, C
- B, C, D
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Identifying the components of DNA:
DNA contains nitrogenous bases like purines (adenine and guanine) and pyrimidines (thymine and cytosine). The structural components shown in the options correspond to these bases.
Option A represents adenine (A), a purine base found in DNA.
Option D represents guanine (G), another purine base found in DNA.
Thus, the correct answer is option (1).
Option A represents adenine (A), a purine base found in DNA.
Option D represents guanine (G), another purine base found in DNA.
Thus, the correct answer is option (1).
