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)recombination.
C)transcription.
D)translation.
E)unwinding.

Question

Quizplus · Accepted Answer

Reduced activity of DNA polymerase I is associated with a deficiency in the activity of DNA excision repair. This repair process is important for correcting damaged DNA sequences. Mutations in genes encoding for DNA polymerase I have been shown to cause a decrease in the excision repair activity of the enzyme.
