What is the Difference Between Nucleotide and Nucleoside?
The key difference between nucleotide and nucleoside is that the nucleotide has a phosphate group while nucleoside lacks that. Other parts like the sugar molecules and nitrogenous bases are common to both, nucleotide and nucleoside. Normally, in living cells, nucleotides are the functional units, not nucleosides. This is because nucleotides are the building blocks of nucleic acids and certain nucleotides serve as the energy currency of the cell. However, nucleosides are also important in medicine since they have anticancer and antiviral properties. So, there is a difference between nucleotide and nucleoside in their fuctions too.
