Question

if the percentage of a bases is 40 percent, what is the percentage of c bases? 10 20 40 60

Explanation:

Step1: Apply base pairing rule

In DNA, A=T and C=G. So %A=%T=40%.

Step2: Calculate remaining percentage

Total bases = 100%. Remaining: $100 - (40+40) = 20\%$.

Step3: Find %C

%G=%C, so %C=$\frac{20}{2}=10\%$.

Answer:

10
