The two functional groups characteristic of sugars are
Carbonyl and phosphate
Carbonyl and methyl
hydroxyl and methyl
Carbonyl and hydroxyl
As we learnt in
Structure of polynucleotide chain -
A nucleotide has 3 components:
1. A nitrogenous base
2. A pentose sugar
3. And a phosphate group
- wherein
Sugar is basically a carbohydrate and carbohydrates are polyhydroxy aldehyde, ketone or their derivatives, which means they have carbonyl and hydroxyl groups.
Option 1)
Carbonyl and phosphate
This is incorrect.
Option 2)
Carbonyl and methyl
This is incorrect.
Option 3)
hydroxyl and methyl
This is incorrect.
Option 4)
Carbonyl and hydroxyl
This is correct.
