Answer:
The correct answer is B.It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment
Explanation:
Hershey and chase in his experiment lebelled the T₂ bacteriophage with radioactive sulfur and radioactive phosphorus separately. Then they infect E.coli with T₂phage and separated phage from bacteria by centrifugation.
Because DNA contains phosphorus not protein, cells infected with phage containing radioactive phosphorous showed radioactivity bacause DNA enters the cell not protein confirming DNA is the genetic material and radioactive sulfur was found in supernatant.
The correct answer is C: Canyon

D. Anaphase Answer b is correct. This is one of the events that occur during anaphase. During anaphase, the cohesin proteins binding the sister chromatids together also break down, and the non-kinetochore spindle fibers lengthen, elongating the cell. Answer a occurs during metaphase, which happens before anaphase.
