Answer: 1000 nucleotides per second.
Explanation: DNA polymerase is an enzyme that catalyzes the addition of new nucleotides to a polynucleotide chain during replication. The rate at which DNA polymerase adds new nucleotides to the growing polynucleotide chain before the DNA polymerase dissociates is called processivity. In E.coli, the rate at which DNA polymerase adds new nucleotides to the growing polynucleotide chain is 1000 nucleotides per second.
