Detailed explanation-1: -For example, DNA polymerase III does most of the elongation work, adding nucleotides one by one to the 3’ end of the new and growing single strand.

Detailed explanation-2: -Primase synthesizes RNA primers complementary to the DNA strand. DNA polymerase III extends the primers, adding on to the 3’ end, to make the bulk of the new DNA.

Detailed explanation-3: -All known DNA polymerases add a deoxyribonucleoside 5′-triphosphate to the 3′ hydroxyl group of a growing DNA chain (the primer strand).

Detailed explanation-4: -DNA polymerase adds nucleotides to the 3’ end of a primer, extending the new chain in a 5’
