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 ... WebWe found that codon 285, a mutational hotspot at a non-CpG site in bladder cancer, is the preferential binding site for N-OH-4-ABP. We also found that C5 cytosine methylation greatly enhanced N-OH-4-ABP binding at CpG sites, and that two mutational hotspots at CpG sites, codons 175 and 248, became preferential binding sites for N-OH-4-ABP only ... WebDNA contains two purines, called adenine and guanine, as well as two pyrimidines, thymine and cytosine. RNA contains similar nucleotides, with the purine uracil found in place of thymine.
