If not repaired by DNA repair enzymes like uracil glycosylase, which cleaves a uracil in DNA, this may result in a point mutation. The Fluid Mosaic Model of the Cell Membrane | What Is the Fluid Mosaic Model? This process is called spontaneous deamination. Within a double-stranded DNA molecule, cytosine bases on one strand pair with guanine bases on the opposite strand. Unlike uracil and thymine that pairs with adenine, cytosine pairs with guanine. The enzyme carbamoyl phosphate synthetase catalyses the formation of carbamoyl phosphate.The catalytic activity of aspartate transcarbamylase converts the carbamoyl phosphate to carbamoyl aspartate. Organic compounds (those containing carbon) with a ring structure containing atoms with carbon, such as sulphur, oxygen, or nitrogen, as part of the ring are known as heterocyclic compounds. Cytosines like other pyrimidine is aromatic and heterocyclic with a single pyrimidine ring which has nitrogen and carbon atoms present in an alternating fashion. Cytosine synthesis starts with carbamoyl phosphate and progresses in a series of steps similar to other pyrimidines. . In RNA, which is made up of cytosine and ribose, the nucleoside of cytosine is cytidine. The cytosine compound may be called differently depending on the various different situations of industrial applications. That leaves cytosine to pair with its double-ringed buddy, guanine. The orientation of the phosphodiester linkage is the same throughout a single strand of nucleic acid, hence, giving a 5'-phosphate end and a 3'-hydroxyl end to a strand. She has extensive experience as a health and science writer and has instruction experience at the college level. 111.10 g/mol. Biochemistry Sixth Edition.
