Question 7

Biology
1 answer:

Answer:

true

Explanation:

Different bacteria like to grow at different temperatures. Thus, a microbiologist will incubate a particular strain of bacteria at its optimal temperature so that he can study it when it is healthy. By changing the temperature, he can study the bacteria while they are stressed. Organisms that grow best at human body temperature, which is approximately 37 degrees Celsius (98.6 degrees Fahrenheit), are called mesophiles. Those that grow in hot temperatures between 40 to 70 degrees Celsius (104 to 158 degrees Fahrenheit) are called thermophiles. Those that grow at hot temperatures above 80 degrees Celsius are hyperthermophiles. Those that live in very cold conditions are called psychrophiles.

Hershey and Chase used a DNA-based virus for their work. How might the results have been different if they had used an RNA virus
4vir4ik [10]

Answer:

The correct answer is c.With an RNA virus, radioactive RNA would have been in the final pellet.

Explanation:

Hershey and Chase infected<em> E.coil</em> with bacteriophage which was having DNA as its genetic material. The bacteriophage was labeled with radioactive sulfur and radioactive phosphorus and it was radioactive phosphorus that was found in the bacterial cells or pellet.  

As because DNA contains phosphorus, not protein therefore they it was proved that DNA is the genetic material. Similarly, RNA is also a nucleic acid which is genetic material for many viruses and contains phosphorus.

So if Hershey and chase might have chosen an RNA virus then radioactive RNA would have been present in the pellet. So the correct answer is c.
