Which component of DNA carries genetic information?

Options

  1. APhosphate group
  2. BSugar backbone
  3. CSequence of nitrogenous bases
  4. DHydrogen bonds

Correct 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
