The basic building block of DNA is the nucleotide. The nucleotide in DNA consists of a sugar (deoxyribose), one of four bases (cytosine (C), thymine (T), adenine (A), guanine (G)), and a phosphate.Cytosine and thymine are pyrimidine bases, while adenine and guanine are purine bases.The sugar and the base together are called a nucleoside.he nucleotide in DNA consists of a sugar (deoxyribose), one of four bases (cytosine (C), thymine (T), adenine (A), guanine (G)), and a phosphate.
Components of DNA. DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a polynucleotide.. Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.There are four different types of nucleotides found in DNA, differing only in the nitrogenous base.The four nucleotides are given one letter abbreviations as shorthand for the four bases.he monomer units of DNA are nucleotides, and the polymer is known as a polynucleotide.. Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
