In the DNA of E. Coli the mole ratio of adenine to cytosine is `0.7`. If the number of moles of adenine in the DNA is 350000, the number of moles of guanine is equal to -

A

`350000`

B

`500000`

C

`225000`

D

`700000`

Text Solution

Verified by Experts

The correct Answer is:
B
`(A)/(C)=0.7`
`(35xx10^(4))/(0.7)=0.7`
`C=(35xx10^(4))/(0.7)=5xx10^(5)`
Moles of cytosine = moles of guanine
