What exactly is a genome?
A compact disc (CD) stores about 4.8 × 109 bits of information in a 96 cm2 area. This information is stored as a binary code—that is, every bit is either a 0 or a 1.
how many bits would it take to specify each nucleotide pair in a DNA sequence?
how many CDs would it take to store the information contained in the human genome?
