3a. (3 pts) Suppose that a genetic mutation occurs in about 1 out of every million bacterial cells. Suppose that you collect a bacterial colony, such that the bacteria divide every minute. Given that after one hour, the bacteria have multiplied into 1x10^18. Of these bacteria, provide an order-of-magnitude estimate of how many would have a mutation.

Solution

THE MUTATION RATE IS 1/10⁶

SO IN 10¹⁸ CELLS THE NUMBER OF CELLS HAVING MUTATION WILL BE POSSIBLY

10¹⁸ / 10⁶ WHIC IS ROUGHLY 10¹² CELLS
