Assuming DNA polymerization by each polymerase in the DNA Pol III holoenzyme proceeds at a rate of 1000 nucleotides per second, how long would anormal E.coli cell take to replicate the entire E .coli chromosome? Under optimal condition, E.coli cells divide every 20minutes. How many replication forks will be present in each E.coli to sustain such a rate of division?

Which of the following statements correctly contrasts DNA pol III with a translesion DNA polymerase, such as DNA pol IV or V? explain the answer please for each statement. 1. Translesion DNA polymerase has low fidelity, while DNA pol III has high fidelity. 2. DNA pol III is highly processive, but translesion polymerases are not. 3. DNA pol III requires a template strand of DNA, unlike translesion polymerases. 4. DNA pol III polymerizes DNA in a 5' to 3' direction,...

1. Why does E. coli need both DNA polymerase III and DNA polymerase I? a. The DNA replication is bidirectional; one polymerase is used for each direction. b. Each polymerase is specific for only one strand of DNA. DNA polymerase III acts only on the leading strand, and DNA polymerase I acts only on the lagging strand. c. Only DNA polymerase I has proofreading ability. d. DNA polymerase III lacks the 5' → 3' exonuclease activity needed to remove RNA...

Scientists decided to study, in vitro, the activity of the eukaryotic DNA polymerase Pol e. 1) In a first experiment, they apply a solution of Pol e on top of a chromatography column containing heparin. They collect the solution that elutes from the bottom of the column (flow-through). Their analysis reveals that the flow-through does not contain any protein. What is the property of heparin demonstrated by this experience? 2) They designed a second experiment including 4 steps. Step 1:...

DNA polymerase III builds new DNA strands in the 5' to 3' direction...always adding the new nucleotide to the 3' end of the existing strand. As it adds new nucleotides, it proofreads its work. If a mistake is detected, DNA polymerase will act as an exonuclease and excise the incorrect nucleotide. A. What supplies the energy needed to add the new nucleotide to the existing chain? B. Please explain why evolution has favored 5’ to 3’ polymerases, as opposed to...

Question: DNA polymerase III is the main DNA-synthesizing enzyme in bacteria. Describe how it carries out its role of elongating a strand of DNA. Answer: DNA pol III determines which free nucleotide triphosphate is complementary to the base being copied. DNA pol III catalyzes phosphodiester bond formation between the alpha phosphate of the incoming nucleotide triphosphate and the 3’ hydroxyl group of the last nucleotide added to the strand. Can someone please explain this step by step in a dumbed...

1. E. coli DNA polymerase V has the ability to bypass thymine dimers. However, Pol V tends to incorporate G rather than A opposite the dam-aged T bases. Would you expect Pol V to be more or less processive than Pol III? Explain. 2. Explain why base excision repair, nucleotide excision repair, and mismatch repair—which all require nucleases to excise damaged DNA—require DNA ligase. 3. Why are there no Pol I mutants that completely lack 5′ → 3′ exo-nuclease activity?
