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.

Comorbid psychosocial symptoms and quality of life in patients with dementia.

Objective: The authors examined the association between treatable comorbid psychosocial symptoms and quality of life (QOL) in patients with dementia. In an effort to develop a more comprehensive understanding of this relationship, this study included both patient reports of their QOL and caregiver reports of patient QOL.
