A "googol" is the term given to the number 10¹⁰⁰ (that is, the number 1 followed by 100 zeros). The DNA molecules in the chromosomes in a human sperm or egg contain approximately 3 × 10⁹ (3 billion) base pairs. How many googol's worth of genetic information could be encoded in human chromosomal DNA molecules?

Answer

806 × 10⁷ googols. In other wor...
