Erwin Chargaff studied the DNA of organismswithin a single species. Chargaff discovered thatthe amount of adenine is about equal
to the amountof thymine. Which of these explains why the ratioof adenine to thymine is nearly 1:1? A Adenine and thymine pair with each other.
B Adenine binds with phosphates, while thymine binds with nitrates.
C Adenine and thymine are identical in chemical composition.
D Adenine bases contain a form of thymine.
<span>A. </span>Adenine and thymine always pair
with each other is the explanation of the discovery of Erwin Chargaff where the
amount of adenine is about equal to the amount of thymine when he studied the
DNA of organisms within a single species.
Adenine and thymine matches with each other explain the why ratio of adenine and thymine is nearly 1:1.Guanine pairs with each other with cytosine.Thymine and cytosine are single ringed(pyrimidine) while adenine and guanine are double ringed(purines)
