Based on laboratory testing, it was discovered that the Doubling Time for E.coli at 25^oC is 40 min. Also, based on laboratory testing, it was discovered that E.coli die at 45^oC.

Fill in the table with the estimated number of bacteria:

Time (min)	0	30	60	120	200	400	600
# of E.coli at 25 oC	1
# of E.coli at 37 oC	1

Time	0	30	60	120	200	400	800
#E.coli at 25° C	1	1	2	8	32	1024	1048576
#E.coli at 37°C	1	1	2	8	32	1024	1048576

Temperature do not affect doubling time between an optimum range. Change in pressure increases the doubling time. So same number of E.coli will be found in 25°Cand 37°C after same time intervals. At 37°C growth rate of E.coli is high.

3. You are working with wild-type cells that have a 16h doubling time. BrdU is a molecule that can be used to measure the amount of DNA inside cells. When added to cell culture, cells will incorporate BrdU into DNA strands during replication as if it were the DNA base thymidine (T). Your general experiment for using BrdU is: 1. Add BrdU to the media and let the cells continue to grow for 16h 2. Harvest cells and label them...
