Chargaff's rule states that in an organism

Options

  1. Aamount of adenine (A) is equal to that of thymine ( T ) and the amount of guanine ( G ) is equal to that of cy
  2. Bamount of adenine (A) is equal to that of guanine (G) and the amount of thymine (T) is equal to that of cytosi
  3. Camount of adenine (A) is equal to that of cytosine ( C ) and the amount of thymine (T) is equal to that of gua
  4. Damounts of all bases are equal

Correct answer

A. amount of adenine (A) is equal to that of thymine ( T ) and the amount of guanine ( G ) is equal to that of cy

Step-by-step solution

Chargaff rule states that in DNA there is always equality in quantity between the bases A and T and between the bases G and C . Related Theory In all the species the molar ratios [A]=[T] and [C]=[G] , and that ratio [C+G] /[A+T] was typically less than the unity with [C+G] is less abundant.
