What kind of bond is formed between the 5' phosphate group (po4) of one nucleotide and the 3' hydroxyl (oh) group of the adjacent nucleotide?

The answer is phosphodiester bond.

That is the bond that is formed between the 5' phosphate group (PO₄ ) of one nucleotide and the 3' hydroxyl (OH) group of the adjacent nucleotide is called phosphodiester bond.

Nucleotide orientation is 5′-to-3′ that is 5' phosphate group (PO₄ ) of one nucleotide and the 3' hydroxyl (OH) group of the adjacent nucleotide .The length of DNA chain doesn't matter for this orientation.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
