Create your account to access this entire worksheet. When a phosphate group adds to the nucleoside, then it will form a compound which will refer to as Nucleotides. When nucleotides connect to form DNA or RNA, the phosphate of one nucleotide attaches via a phosphodiester bond to the 3-carbon of the sugar of the next nucleotide, forming the sugar-phosphate backbone of the nucleic acid. In signal transduction, a cell produces a signal in response via modifying cellular activity and gene expression. Why does the phosphate group have a net charge of -2? Nucleotides can pair up with each other: cytosine always pairs with guanine, and adenine pairs with thymine in DNA or uracil in RNA. List the components of a nucleotide. The liver is the major organ of de novo synthesis of all four nucleotides. You may be asked to name the three parts of a nucleotide and explain how they are connected or bonded to each other. On below, a table is given where a nomenclature of Deoxyribonucleotide is given where a single phosphate group is added to the deoxyribonucleoside.
