The components of a nucleoside are:

A pentose sugar(generally ribose or deoxyribose), and

a nitrogenous base which may be Adenine/Guanine/Thymine/Cytosine/Uracil.

It becomes a nucleotide on addition of a phosphate group.

The number of nucleotides (and base pairs) varies from species to species. However, the number of DIFFERENT nucleotides is 4: - adenine nucleoside phosphate - cytosine nucleoside phosphate - guanine nucleoside phosphate - thymine nucleoside phosphate


A nucleoside (with an s) is a nitrogenous base covalently attached to a (ribose or deoxyribose) sugar but does not have a phosphate group attached.A nucleotide (with a t) consists of a nitrogenous base, a sugar, and aphosphate group.So, a nucleotide is a "nucleoside mono-phosphate" or a nucleoside with a phosphate group attached.


a nucleoside consist of base and sugar but a nucleotide consist of base sugar and phosphate group


the nucleoside triphosphates have the sugar deoxyribose; ATP has the sugar ribose


Nucleoside contains a sugar group and a base whereas phosphorylation of nucleosides by kinases ( addition of phosphate in the sugar's primary alchohol group) produces nucleotides.nucleoside = sugar +basenucleotide = sugar + base + phosphate


The components are a nitrogenous base, a five-carbon sugar, and a phosphate. The nitrogen compound is called a nucleobaseand combines with the sugar to form the nucleoside, and the phosphate binds to the carbon in the sugar.


yes, nucleoside analogues are artificial nucleosides. The block the completion of new viral DNA chains, therefore, preventing the production of new viral bodies. This way the viral enzyme, reverse transcriptase is more likely to incorporate the nucleoside analogue into the DNA than the host's DNA polymerase.

They have a different mode of action in inhibiting the transcription of the viral DNA. The NRTI is actually a nucleoside that incorporates into the viral DNA but it does not have a 3-hydroxyl group so it inhibits and halts the continued growth of the viral DNA chain. The NNRTI's bind to the reverse transcriptase and inhibit its movement.

A nucleoside consists of a nitrogenous base and a five-carbon sugar molecule. A nucleotide consists of a nitrogenous base, a five-carbon sugar molecule, and a phosphate group (made of one phosphorus atom and four oxygen atoms). This added phosphate group is what allows nucleotides to bond together to form long chains.
