Oxidative deamination of adenine produces hypoxanthine (the base of inosine), which can base pair with cytosine. (a) If no repair takes place, describe the makeup of the DNA in the two daughter cells following cell division. (b) Describe the makeup of the DNA in the four daughter cells following a second round of cell division.
Explain why base excision repair, nucleotide excision repair, and mismatch repair—which all require nucleases to excise damaged DNA—require DNA ligase.
What type of repair system would cells most likely use to repair DNA with a deaminated adenine?
A composite transposon integrated in a circular plasmid occasionally transposes the DNA comprising the original plasmid rather than the transposon’s central region. Explain how this is possible.
