A) G/34%, A/24.5%, T/24.5%
B) G/17%, A/16.5%, T/32.5%
C) G/17%, A/33%, T/33%
D) G/8.5%, A/50%, T/24.5%
Correct Answer: C
Solution :
Chargaffs rule states that purine and pyrimidine base paires are present in equal amount, i.e. A = T, G = C. (A + T) = (G + C) \[\therefore \] \[\frac{A+T}{G+C}=1\] Cytosine = 17% If \[A+G+C+T=100\]and \[G=C,\,\,\,A=T\]Then \[A+17+7+T=100\] \[\therefore \] \[G=17%\] \[A+T+34=100\] \[A+T=100-34\] \[A+T=66\] \[A=T=33%=66\] Hence, if cytosine is 17%, then G = 17% A and T will be 33% each.You need to login to perform this action.
