The bonds found in a polynucleotide chain between the individual nucleotides and nitrogen bases
1 Peptide bond, Hydrogen bond
2 Hydrogen bond, Peptide bond
3 Phosphodiester bond, Hydrogen bonds
4 Glycosidic bond, Phosphodiester bond
Explanation:
Exp: C The bonds found in a polynucleotide chain between the individual nucleotides and nitrogen bases are phosphodiester bond and hydrogen bonds. Phosphodiester bonds are covalent bonds that are formed between the phosphate group of one nucleotide and the hydroxyl group of the sugar of the next nucleotide in a linear chain while hydrogen bonds forms between nitrogenous bases of the nucleotides. These bonds are weak bonds. Hydrogen bonds hold the two strands of the DNA helix together.
