Question

Based on the DNA base pairing rules,would cells always have the same amount of cytosine and adenine molecules?

Answer 1

In the late 1940s, Chargaff analyzed the proportions of the four different types of base molecules in DNA, and found that DNA always contains equal amounts of guanine and cytosine, and equal amounts of adenine and thymine.

Step-by-step explanation:

Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C ) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
