What is the difference between a nucleotide and nucleoside? Give two examples of each with their structure.

(N/A) nucleoside is formed by the combination of a pentose sugar and a nitrogenous base. In contrast,a nucleotide is formed when a nucleoside is linked to a phosphate group.
Key differences:
$1$. Composition: Nucleoside = Sugar + Nitrogen base; Nucleotide = Sugar + Nitrogen base + Phosphate group.
$2$. Examples of Nucleosides: Adenosine,Guanosine.
$3$. Examples of Nucleotides: Adenylic acid $(AMP)$,Guanylic acid $(GMP)$.
Structure:
- Adenosine (Nucleoside): Consists of Adenine attached to a ribose sugar at the $1'$ position.
- Adenosine monophosphate $(AMP)$ (Nucleotide): Consists of Adenine attached to a ribose sugar at the $1'$ position,with a phosphate group attached to the $5'$ carbon of the sugar.
