Answer:
Explanation:
One of the earlier experiments that confirmed DNA and not proteins as genetic material was conducted by Alfred Hershey and Martha Chase
Hershey and Chase experiment showed the genetic material of virus is DNA not protein. Their experiments demonstrated that Phage are composed of DNA and protein, when phage infect bacteria, their DNA enters the host bacterial cell but not protein before infection
Hershey and Chase experiment prove that DNA is the hereditary material.
From chargaff base pairing rule, the ratio of purine to pyrimidine is a cell is 1:1. Since adenine pair with thymine and cytosine pair with quanine, this means the percentage of adenine will equal the percentage of thymine.
%A = %T and %G = %C.
%A + %T + %G + %C =100
If a DNA contains 8% adenine, therefore the percentage of thymine is 8%
8% + 8% + %G +%C = 100%
16% + %G +%C = 100%
%G +%C = 100%-16%
%G +%C = 84% = 84%/2= 42%
Since %G = %C
Then %G = 42%, %C = 42
