Question 1
RecA is involved in the bacterial SOS response to DNA damage by:
◦ directly cleaving the LexA protein.
◦ catalyzing general protein degradation.
◦ catalyzing recombination repair.
◦ activating autocleavage activity of itself.
◦ activating autocleavage activity of LexA.
Question 2
Replication forks that are stalled at damaged regions of DNA can be restarted by:
◦ the RecBC system.
◦ the RecF system.
◦ the UvrABC system.
◦ the UmuD system.
◦ the NHEJ system.
