How does recombinational repair differ from nucleotide excision repair (NER)?

#Unit 8. Inheritance Biology

  1. Unlike NER, recombinational repair is unable to repair damage caused by thymine dimers.

  2. NER replaces the thymine dimmer while recombinational repair leaves it in place.

  3. NER requires DNA polymerase and ligase function, while recombinational repair does not.

  4. NER involves nick translation, which recombinational repair does not.

Host-pathogen interactions are an ongoing arms race; pathogens evolve to express unique structures that avoid host detection, and the host germline-encoded recognition system co-evolves to match these new challenges. However, because pathogens generally have much shorter life cycles than their vertebrate hosts, and some utilize error-prone DNA polymerases to replicate their genomes, pathogens can evolve rapidly to evade host encoded recognition systems. Which error prone DNA polymerase is used  by human?
