Nucleic Acids

Question 1

Nucleoside and bond used

Answer 1

Nitrogenous base joined to sugar by glycosidic bond

Question 2

Bonds used in nucleotide

Answer 2

Nitrogenous base and sugar molecule joined by glycosidic bond
Nucleoside combines with phosphate by ester bond to form nucleotide
Phosphate moiety links 3’ C of 1 sugar of 1 nucleotide to 5’ C of succeeding nucleotide
Bond formed b/w phosphate and hydroxyl group of sugar is ester bond.
One such ester bond on each side - phosphodiester bond
