Suppose that under the conditions of an experiment, a particular virus has an expected substitution rate of 1 per 2,000 nucleotides per generation and a genome size of 10,000 nucleotides.The virus has one generation per hour.We would expect _______ substitutions between 9:00 am on Monday and 1:00 pm on Friday of the same week.

The virus has a substitution rate of 1 per 2,000 nucleotides per generation. With a genome size of 10,000 nucleotides, this means 5 substitutions per generation (10,000/2,000). From 9:00 am Monday to 1:00 pm Friday is 100 hours (4 days and 4 hours), which equals 100 generations. Therefore, 5 substitutions per generation over 100 generations result in 500 substitutions.
