WebThe deoxyribose sugar is attached to a phosphate group and to a nitrogenous base. The base may be any one of four possible options: cytosine (C), thymine (T), adenine (A), and guanine (G). The four bases have differences in their structure and functional groups. Cytosine and thymine are pyrimidines and have just one ring in their chemical ... WebMay 31, 2024 · In DNA, adenine always pairs with thyine and cytosine always pairs with guanine. These pairings occur because of geometry of the base,s allow hydrogen bonds to form only between the “right” pairs. Adenine and thymine will form two hydrogen bonds, whereas cytosine and guanine will form three hydrogen bonds.
WebCytosine deamination appears to be largely responsible for spontaneous mutations in the modern world. Because of its sensitivity to temperature (Q 10 = 4), that reaction would have furnished a mechanism for rapid evolution on a warm earth. As the temperature fell from 100° to 25 °C, the rate of cytosine-based mutation would have fallen by a factor of more … WebJul 15, 2024 · Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine. This rule is named after the scientist Erwin ...
