Nucleotides are added at an approximate rate of 50 nucleotides per second in eukaryotic cells. The human genome contains 6.4 billion nucleotides (3.2 billion base pairs), which must be copied. Calculate the length of time in days that it would take to copy the human genome. Show all calculations including units.

what do the different brain waves do?

explanation:
