Question

difference between nucleotide and nucleoside?

Answer 1

Nucleoside vs. Nucleotide. Anucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. A nucleotideconsists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups.

Answer 2

Nucleotides are organic molecules that serve as the monomer units for forming the nucleic acid polymers deoxyribonucleic acid and ribonucleic acid, both of which are essential biomolecules within all life-forms on Earth.

______________________________________________________

Nucleosides are glycosylamines that can be thought of as nucleotides without a phosphate group. A nucleoside consists simply of a nucleobase and a five-carbon sugar, whereas a nucleotide is composed of a nucleobase, a five-carbon sugar, and one or more phosphate groups.
