2. Hydrogen
3. 2 hydrogen
4. 3 hydrogen
Explanation:
1. Deoxyribonucleotides bind together to form polynucleotides. This bond occurs between the phosphate group of one nucleotide and the C- 5' position of a 3 of another nucleotide. The type of bond formed in this interaction is called a PHOSPHODIESTER bond.
2. The nitrogenous bases of each nucleotide project the double helix. They form complementary base pairs through the formation of HYDROGEN bonds with bases on the opposite DNA strand.
3. Adenine complementarily binds with thymine and forms TWO HYDROGEN bonds bonds.
4. Guanine complementarily binds with cytosine and forms THREE HYDROGENbonds bonds.
