In the Hershey-Chase experiment, bacterial viruses, called phage, were used to demonstrate that DNA is the genetic material. The phage that were used for this experiment consisted of DNA surrounded by a protein coat. Phage will attach to specific types of bacteria and inject their DNA into the bacterial cell. To scientifically determine whether DNA is the genetic material, Hershey and Chase made phage in a medium containing radioactive sulfur-35 (S35). Why was S35 used in this experiment

Respuesta :

Answer:

  • Options-
  1. The phage that were used for this experiment consisted of DNA surrounded by a protein coat.
  2. Phage will attach to specific types of bacteria and inject their DNA into the bacterial cell.
  3. To scientifically determine whether DNA is the genetic material, Hershey and Chase made phage in a medium containing radioactive sulfur-35 (S35).

Explanation:

  • The options which are mentioned above are the main reason behind the use of the phage inside the experiment which was performed, as the genetic material defined the existence of the living body in a given space and provide much information regarding the whole genetic makeup as well in a given situation.
