Recombination
- three types of recombination (strand exchange)
- homologous - requires extensive sequence homology
(chromosomal recombination)
- Holliday model
- homologous pairing
- nicks on two different strands exchange and
ligation between different strands
- branch migration
- nick opposite strands and ligate
- gene conversion - a non-reciprocal exchange
- a consequence of branch migration and
excision repair
- site-specific - always occurs at the same location
(viruses)
- illegitimate - not site specific (transposons)
