MHT CET Chemistry Question (2026) — Solution
Options
- A. Phosphate group
- B. Sugar backbone
- C. Sequence of nitrogenous bases
- D. Hydrogen bonds
Answer
C. Sequence of nitrogenous bases
Step-by-step solution
The genetic information in DNA is stored in the specific sequence of its nitrogenous bases (adenine, thymine, cytosine, and guanine). The sugar and phosphate groups form the structural backbone of the DNA molecule, while hydrogen bonds hold the two complementary strands together. Therefore, the sequence of nitrogenous bases is responsible for carrying genetic information. Answer: Sequence of nitrogenous bases
