- Are living things only the product of their DNA? Why or why'not?
Darina [25.2K]

Answer:

No, since DNA does code for certain traits, others are introduced or changed by the environment. For example, some adaptations are not coded in DNA, such as dying hair. According to the gene, hair is to be black, for example, but it can be changed to look pink. Another example is when a person is first born. When they are, some bacteria enter the system of the baby --- mostly good. Then the baby's gut will be different, and the bacteria in the gut are not coded by the DNA. So, living things are not only the product of DNA, as there are extraneous factors that affect living things as well.

Explanation:

Phew, that was long! Hope this helps (:

How did Hershey and Chase ""label"" viral DNA and viral protein so that they could be distinguished? Explain why they chose each
vlabodo [156]

Answer:

As DNA contain phosphorus in its structure in large amount, therefore, Harshey and Chase labeled DNA with radioactive phosphorus and because protein contains some amino acids which have sulfur so they labeled T2 bacteriophage protein with sulfur.

So after that they infected E.coli bacteria with radioactively labeled phages and after centrifugation, they have found that pellet which contains cells is showing the presence of radioactive phosphorus and supernatant which have T2 phage capsid protein showing the presence of radioactive sulfur.

Therefore by labeling viral protein and viral DNA they found that DNA is the genetic material not protein.
