List four enzymes known to be involved in the replication of DNA in bacteria
There are many enzymes involved in bacterial replication:
Few of them are listed below with their function.
DNA polymerase I - The function of DNA pol I is to replace RNA primers with DNA. It functions as an exonuclease.
DNA polymerase III - It acts as the main DNA synthesis enzyme (adds nucleotides in the 5′ to 3′ direction).
Helicase - It helps in unwinding of DNA double Helix.
Ligase - It works by filling/ sealing the gaps between the Okazaki fragments on the lagging strand such as to create one continuous strand.
Primase - help in synthesizing RNA primers ( to start replication)
Gyrase is involved in relieving the Stress on DNA during unwinding by creating breaks.

Describe the structure of DNA List the steps involved in DNA Replication What is crossing over? (Honors Only) What occurs during nondisjunction? What is a monosomy, and a trisomy? Give examples of disorders caused by each.
Which of the following is not a correct description of DNA replication in bacteria? Replication is semiconservative Replication is discontinuous Replication is dispersive Replication begins at the origin of replication and proceeds bidirectionally
Bacteria use restriction enzymes to: O A. Conjugate OB. transcribe DNA OC. Defend themselves against bacteriophage (virus) OD. link the okazaki fragments produced during DNA replication Reset Selection Mark for Review What's This?
26. Topoisomerases are enzymes that support DNA replication in prokaryotes and eukaryotes. These enzymes have been used as targets for drug development. Answer the following questions on topoisomerases: (a) What are topoisomerases, what do they do, and how do they support DNA replication? (4 marks) (b) What is the difference between topoisomerase I and II? (2 marks) (c) Why is topoisomerase II an attractive drug target for bacterial pathogens? (2 marks)
in eukaryotic dna replication is there 1 replication fork and is there where dna replication starts how about bacteria dna replication is there 1 replication fork and what does it mean when baxterial dna replictes at the dna what are the structural and molecular differences between eukaryotic and bacterial dna replication
DNA mismatch repair enzymes preferentially repair bases on the newly synthesized DNA strand, using the old DNA strand as the template. If mismatches were simply repaired without regard for which strand served as template, would this reduce replication errors? Explain your answer (5 pts) Describe DNA replication (remember to mention all the enzymes involved) (10 pts)
