If a dsDNA has 30% thymine, what is the percentage of That is- A=T & C= G. Cytosine pairs with guanine and adenine pairs with thymine. 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. There are four DNA nucleotides, each with one of the four nitrogen bases (adenine, thymine, cytosine, and guanine). If a dsDNA has 30% thymine, what is the percentage of cytosine present?
