Chlamydomonas chloroplasts can use short dispersed repeats and multiple pathways to repair a double-strand break in the genome

Certain group I introns insert into intronless DNA via an endonuclease that creates a double-strand break (DSB). There are two models for intron homing in phage: synthesis-dependent strand annealing (SDSA) and double-strand break repair (DSBR). The Cr.psbA4 intron homes efficiently from a plasmid in...
