Question

What is nucleoside?

Answer 1

Nucleosides have 2 parts:

1. A nitrogenous base
2. A sugar. Either ribose, or deoxyribose.

Those two parts are attached to one another.

Answer 2

Nucleosides are the form of nucleotides?

Answer 3

You can say that... just remove the phosphate groups.

Answer 4

A good known example would be to take Adenosine (a nucleoside). Add 3 phosphate groups and we get ATP a nucleotide.

Answer 5

They're almost the same thing.

There's one difference.

Here's a picture of a NUCLEOTIDE:

You see how it has THREE parts?
1. Nitrogen base
2. Sugar
3. Phosphase group

That's a NUCLEOTIDE.

A nucleoside only has two of those parts:
1. Nitrogen base
2. Sugar
