A double-stranded DNA molecule with 20% thymine would contain 30% guanine. The hereditary material in an organism is carried by DNA. In 1950, Chargaff noticed that, when separated, the purines (adenine and guanine) always existed in a 1:1 ratio with the pyrimidines (thymine and cytosine). As a result, Thymine's percentage rises to 30%. What is the amount of guanine in DNA if the Strand had was made of 10% thymine? Adenine always bonds or pairs with Thymine, while Guanine always bonds or pairs with Cytosine. So cytosine will make 20% and guanine will make 20% of nucleotide in the DNA. If 30% of the bases in human DNA are thymine The amount of guanine is 28%. Guanine (G) in DNA is one-to-one coupled to cytosine (C), so that also makes up for 10%. From 100% DNA bases subtract 40%.
