Question

What is the difference between nucleotide and nucleoside?

Answer 1

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.

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 triphosphate	Example- adenosine.
