describe the components and structure of a dna nucleotide
A nucleotide consists of three components:   1. A 5-carbon sugar (deoxyribose for DNA or ribose for RNA)   2. A nitrogenous base (adenine, cytosine guanine and thymine (â¦ or uracil in RNA)   3.A phosphate group.he three components that create a DNA nucleotide are a phosphate group, a nitrogenous base [this will be either Adenine, Guanine, Cytosine, or Thymine], and a Sugar [deoxyrib â¦ ose, which is how we get the D in DNA]. 5 people found this useful.

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.
