It is stated int The Chargaff’s rule that DNA from any cell of organisms must have the ratio 1:1, following the base pair rule that:
A=T G=C
Where, A is adenine, T is thymine, G is guanine and C is cytosine.
So we have; 36 Adenine = 36 Thymine
24 Cytosine = 24 Guanine
The answer to this item then is 36 thymine.
