Question

What would be the percentage of thymine in a double stranded DNA sample- which contains 20- cytosine of the total bases-20-10-30-40-

Toppr Admin · Accepted Answer

According to Chargaff-apos-s rule-Guanine -purine- - Cytosine -pyrimidine- andAdenine -purine- - Thymine -pyrimidine-Therefore- Guanine would be 20- and total of G-C - 40- and hence A-T would be 60- that is 30- each- Hence- option C is correct answer-

According to Chargaff's rule:Guanine (purine) = Cytosine (pyrimidine) andAdenine (purine) = Thymine (pyrimidine)Therefore, Guanine would be 20% and total of G+C = 40% and hence A+T would be 60% that is 30% each. Hence, option C is correct answer.

According to Chargaff's rule:
Guanine (purine) = Cytosine (pyrimidine) and
Adenine (purine) = Thymine (pyrimidine)
Therefore, Guanine would be 20% and total of G+C = 40% and hence A+T would be 60% that is 30% each. Hence, option C is correct answer.
