If there are many more acidic residues than basic ones, the protein will have an overall negative charge. ....it is the phosphate groups that contain a negatively charged oxygen atom that make the DNA n RNA molecules negatively charged......
Overview [edit]. A DNA nucleotide is composed of 3 main units: a sugar, a phosphate group, and a nitrogenous base. While the sugar and phosphate group alternate in sequence and form the backbone of the DNA double helix, the nitrogenous bases may differ in every adjoining nucleotide.The four nitrogenous bases present in DNA are adenine (A), guanine (G), cytosine (C) and thymine (T).In RNA, the only differing nitrogenous base is uracil (U) (which replaces thymine in DNA and differs thymine only by the missing methyl group at carbon 5 of the pyrimidine ring).hile the sugar and phosphate group alternate in sequence and form the backbone of the DNA double helix, the nitrogenous bases may differ in every adjoining nucleotide. The four nitrogenous bases present in DNA are adenine (A), guanine (G), cytosine (C) and thymine (T).
