The Energetic Cost of Mismatch Repair. In an E. coli cell, DNA polymerase III makes a rare error and inserts a G opposite an A residue at a position 650 bp away from the nearest GATC sequence. The mismatch is accurately repaired by the mismatch repair system. How many phosphodiester bonds de- rived from deoxynucleotides (dNTPs) are expended during this repair
