What is a nucleotide made of?

Nucleotides are the building blocks of nucleic acids; they are composed of three subunit molecules: a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group. They are also known as phosphate nucleotides. A nucleoside is a nitrogenous base and a 5-carbon sugar.

Simply so, what is a nucleotide of DNA?

Nucleotide Structure. 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.

What are the three parts of a nucleotide of DNA?

Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts:
  • Nitrogenous Base. Purines and pyrimidines are the two categories of nitrogenous bases.
  • Pentose Sugar. In DNA, the sugar is 2'-deoxyribose.
  • Phosphate Group. A single phosphate group is PO43-.
