The condensation reaction that forms nucleic acid polymers occurs between a group on one nucleotide and a group on a second nucleotide. a. phosphate, hydroxyl b. carbon, carbonc. nitrogenous base, sugar d. nitrogenous base, nitrogenous base

a. Posphate and hydroxyl

Explanation:

Hydroxyl group on carbon No.5 of ribose or deoxyribose on one nucleotide will react with hydroxyl group on phosphate on another nucleotide. Phosphodiester bond is formed by condensation reaction which is called as esterification.

Enzymes involved are DNA polymerase and DNA ligase in DNA replication

and RNA polymerase and ligase in RNA transcription

DNA has deoxyribose

RNA has ribose

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
