If Adenine makes 30% of the DNA molecule, what will be the percentage of Thymine, Guanine and Cytosine in it ? (1) T : 30 ; G : 20 ; C : 20 (2) T : 20 ; G : 25 ; C : 25 (3) T : 20 ; G : 30 ; C : 20 (4) T : 20 ; G : 20 ; C : 30
Option A is correct ans Thymine −30%, Guanine −20%, Cytosine −20% (Chargaffs nitrogen base pairing rule which states that amount of Adenine is equal to Thymine and Guanine is equal to Cytosine.
