Fig 16-14 What is the “synthesis” reaction to build the DNA strand? (What is being added to what? Where does the energy come from for this synthesis?) •  DNA polymerases adds nucleotides to the 3' end of a strand of DNA. If a mismatch, the polymerase halts. •  Proofreading removes the mismatched nucleotide and extension continues. DNA polymerase adds the 5’ phosphate of the new nucleotide to the 3’ sugar of the growing chain. Explain each of these: –  Condensation - Complementary Base Pairing –  Endergonic - Proofreads DNA polymerase is wonderful; it...
