Nucleoside

Q. In nucleoside, where is the nitrogenous base attached to the pentose sugar?

1. Carbon-5' of pentose sugar
2. Carbon-1' of pentose sugar
3. N-1 and N-9
4. Both B and C

Q. A nucleoside is formed through an N-glycosidic linkage by joining:

1. Phosphate group with nitrogen base
2. Nitrogen base with nitrogen base
3. Nitrogen base with pentose sugar
4. Pentose sugar with phosphate group

Q.

A single nucleoside consists of

1. Sugar + Nitrogenous base

2. Nitrogenous base + Phosphate group

3. Sugar + Phosphate

4. Sugar + Nitrogenous base + Phosphate
