Q33 / 160 · AP EAMCET 2024 (21 May Shift 2) · Chemistry

Given below are two statements Statement I: Cytosine and guanine are formed in equal quantities in DNA hydrolysis Statement II: Adenine and uracil are formed in equal quantities in RNA hydrolysis The correct answer is

  • A
    Statements I, II both are correct
  • B
    Statements I, II both are incorrect
  • Correct answer
    C
    Statement I is correct but statement II is incorrect
  • D
    Statement I is correct but statement II is correct

Solution

Chargaff's rule state that in DNA of any species and any organism, the amount of guanine should be equal to the amount of cytosine and the amount of adenine should be equal to the amount of thymine. So statement (I) is correct but (II) is incorrect.

Hence, the correct answer is option: 'C'.
