If A and C make 30 % and 20 % of DNA, respectively, what will be the percentage composition of T and G ?

Options

  1. AT : 20 %, G : 30 %
  2. BT : 30 %, G : 20 %
  3. CT : 30 %, G : 30 %
  4. DT : 20 %, G : 20 %

Correct answer

B. T : 30 %, G : 20 %

Step-by-step solution

aligned & A 30 %= T 30 % & C 20 %= G 20 % aligned According to chargaff's rule, Adenine (A) pairs with Thymine (T) and Cytosine (C) pairs with Guanine (G). So, The ds DNA have equal percentage of A and T or G and C .
