What is the difference between nucleotide and nucleoside?


Open in App
Solution

DNA ( Deoxyribonucleic acid):

  1. DNA consists of a long polymer of deoxyribonucleotides.
  2. Every deoxyribonucleotide consists of deoxyribose sugar, nitrogenous base, and phosphoric acid.
  3. Nucleotide acts as a monomer in the formation of DNA.
  4. Nucleoside gets combined with a phosphate group to form a single nucleotide.
Nucleotide: Structure, Examples and Function

Difference between nucleotide and nucleoside:

Nucleotide

Nucleoside

A phosphodiester bond connects a phosphate group to a nucleoside to make a nucleotide.A nucleoside is formed when a nitrogenous base reacts with the C-atom-1 of deoxyribose sugar. The N-glycosidic bond holds them together.
It is made up of nucleotides that have been phosphorylated.It is a nucleotide component
It is acidic in nature.It is slightly basic in nature.
It acts as a precursor of DNA, RNA, and polynucleotide.It serves as a precursor of nucleotide.
Example-adenine triphosphateExample- adenosine.
