Question

If a DNA molecule contains a total of 600 bases and 20% of the bases are cytosine, how

Answer 1

Answer:

We know that there are 200 guanine bases so there will be 200 cytosine bases also.

According to Chargaff’s base pair rule,

G+A=T+C=600,

A+200+T+200=600 (since total bases are 600)

A+T+400=600

A+T=200

since there is 50% adenine and 50% thymine , A=100, T=100, G=200, C=200

Verification

A+T+G+C=600

100+100+200+200=600

600=600
