An isolate of a mutant bacterium appears to grow more slowly than the population (wild type)from which it was isolated. Further studies showed that the slower growth was due to a markedly reduced DNA polymerase I activity. From this information, one would expect that this organism would also be deficient in the activity of DNA
A)excision repair.
B)transcription.
C)recombination.
D)unwinding.
E)translation.
