A compact disc $($CD$)$ stores about $4\mathrm{.}8{10}^9$ bits of information in a $96c{m}^2$ area. This information is stored as a binary code$-$that is$,$ every bit is either a $0$ or a $1.$

A$.$ How many bits would it take to specify each nucleotide pair in a DNA sequence?

B$.$ How many CDs would it take to store the information contained in the human genome?
