If a bacterium has a generation time of 30min and you start with 100cells at time 0, how many cells will you have in 30min
We will have 200 cells: bacteria will divide once during 30 minutes, so number of the cells will be 100x2 = 200.

If you inoculate 1*10^6 CFU/ml E.coli, assuming a population doubling time of 20 minutes. Calculate the total number of cells present in a 100 ml flask of LB broth after 6 hours.
Initially, the number of cells was 1*10^6 CFU/ml * 100 ml = 1*10^8 CFUThe number of 20-minutes intervals in 6 hours is 18.The expected number of bacteria is 2^18*1*10^8 = 262144*10^8. It is approximately...

Binary Fission in bacteria if very fast, sometimes doubling every 20 minutes. If bacteria can divide every 20 minutes how many bacteria would there be after 4 hours if there were originally 100?
As bacteria divide every 20 minutes for 4 hours, the number of their division equals:4h / 20min = 240min / 20min = 12 divisionsThe number of bacteria after 12 divisions...

Root cells in a plant completely lack chloroplasts, whereas leaf cells have many chloroplasts. Which difference will be seen in these two types of cells?
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.Therefore, leaf cells are capable to perform photosynthesis, and root cells - cannot...

The initial concentration of cell culture is 500 cells per mL. After 3 hours, the of cells in one mL is 2,56,000. calculate the generation time of cells
The generation time is the time interval required for the cells (or population) to divide.G (generation time) =t (time, in minutes)/n(number of generations)G = t/nt = time interval in minutes = 180...

If a lacI - bacterium is grown in the presence of the sugar X-gal, a blue dye appears; however, the concentration of X-gal decreases over time. What has happened to the X-gal?
Lac operon is operating in bacteria which consist of promoter, operator, regulator and a terminator. Operator region has 3 structural genes lacZ, lacY, and lacA.X-gal is an organic compound consisting...
