Question

Hershey and Chase were the first two scientists to prove that genetic material is composed of proteins. & Chargaff observed that the amount of adenine in an organism always equaled the amount of thymine.

Select one:
a. T&F
b. F&F
c. T&T
d. F&T

Answer 1

Hershey and Chase's experiments confirmed that DNA is the genetic material, and Chargaff's rules state that the amount of adenine always equals the amount of thymine.

Step-by-step explanation:

Hershey and Chase's experiments using the bacteriophage T2 confirmed that DNA is the genetic material, not proteins. They found that the DNA of the bacteriophage was injected into the host cell and replicated, proving that it carried the hereditary information. Erwin Chargaff later observed that the amount of adenine always equaled the amount of thymine in DNA, and the amount of cytosine always equaled the amount of guanine, known as Chargaff's rules.
