Thymine (T) pairs with Adenine (A) and Cytosine (C) pairs with Guanine (G). 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. So if Thymine is 30% then Adenine is 30% 60% total. In #"DNA"#, adenine #("A")# always bonds with thymine #("T")#, while guanine #("G")# always bonds with cytosine #("C")#. is 30 If the percentage of thymine is 30% what would the WebSolution.
