With reference to the mechanisms of mismatch repair and nucleotide-excision repair in E. coli cell, which mechanism is more energy costing? Explain your answer.

Explain the following repair mechanisms: -removal of thymine dimers -base excision repair -nucleotide excision repair.

Match each DNA repair mechanism with its description. photoactive repair base excision repair nucleotide excision repair mismatch repair SOS system nonhomologous end-joining A. recognizes newly synthesized but improperly paired DNA and nicks the strand to replace B. cuts a piece out of distorted DNA to be filled in by polymerase C. an emergency, error-prone effort to salvage replication of damaged DNA D. removes and replaces depurinated or deaminated bases from sugars E. repairs pyrimidine dimers in the presence of light...

Compare and contrast the processes of base excision repair and methyl-directed mismatch repair in prokaryotes. In your answer discuss: a) Under which circumstances this mechanism will need to be used in the cell. b) The sequence of events that occur in the repair process. c) The names and roles of the enzymes involved in each repair mechanism.

In the mismatch repair system, the MutS protein initiates the repair process, and the MutHL excision complex acts by cutting A) The methylated strand of the double helix B) Any U:A base pairs found in the DNA C) Any G:T base pair D) The non-methylated strand of the double helix E) The site of the helix distortion

During the mismatch repair of DNA, the repair enzyme will remove several nucleotides on both DNA strands. will remove several nucleotides on one DNA strand. will remove only the mismatched nucleotide. will remove the mismatched nucleotide, and the same enzyme will replace it with the correct nucleotide. is unable to detect mutations.

During mismatch repair, how does the cell “know” which strand to degrade and repair? Why will it lose this ability after a certain amount of time? Provide a reason that might explain why it is safer to degrade the new strand of DNA rather than the parental strand.
