A) a scientist cultures e. coli in the presence of a radioactive phosphate source. after growing the culture for 2 hours, she grinds up the e. coli and separates the bacterial dna from the proteins. which sample will contain most of the radioactivity and why?
b) the experiment is repeated, but this time, the bacteria are grown in the presence of radioactive sulfate instead of phosphate. which sample will contain the radioactivity and why?

2. to determine if the type of agar affects bacterial growth, a scientist cultures e. coli on four different types of agar. five petri dishes are set up to collect results: • one with nutrient agar and e. coli • one with mannitol-salt agar and e. coli • one with macconkey agar and e. coli • one with lb agar and e. coli • one with nutrient agar but no e. coli all of the petri dishes received the same volume of agar, and were the same shape and size. during the experiment, the temperature at which the petri dishes were stored, and at the air quality remained the same. after one week the amount of bacterial growth was measured.

As a scientist, you seek to prove that dna is the hereditary macromolecule by replicating the hershey-chase experiment. you culture the lambda phage in heavy and light cl (cl-36 is heavy and radioactive - the most abundant is cl-35, lighter and non-radioactive). you purify the phage from their growth media and infect the e. coli, where will you detect radioactivity? select one: a. within the e. coli pellet as the dna has entered the bacterial cells. b. on the e. coli cell surface (or phage fraction), as part of the phage protein coat. c. in the supernatent (free liquid) of your test tube d. both a and b e. none of the above why is the answer none of the above? why cant the radioactivity be detected?

In the b-galactosidase assay, it is important to measure the density of e. coli cells because select one: a. the lac operon is induced only in a small percentage of cells in a culture. b. the transformation efficiency of e. coli cells is low. c. e. coli densities vary among cultures and with time, which will affect estimates of b-galactosidase production rates. d. onpg production by e. coli is a function of cell density. e. we are measuring per cell cleavage of x-gal in relation to culture conditions and time.
