The correct answer is:
500000
$\begin{array}{l}
\frac{A}{C}=0.7 \\
\frac{35 \times 10^{4}}{C}=0.7 \\
C=\frac{35 \times 10^{4}}{0.7}=5 \times 10^{5}
\end{array}$
Moles of cytosine $=$ moles of guanine
\frac{A}{C}=0.7 \\
\frac{35 \times 10^{4}}{C}=0.7 \\
C=\frac{35 \times 10^{4}}{0.7}=5 \times 10^{5}
\end{array}$
Moles of cytosine $=$ moles of guanine
