The Fragile Breakage versus Random Breakage Models of Chromosome Evolution
For many years, studies of chromosome evolution were dominated by the random breakage theory, which implies that there are no rearrangement hot spots in the human genome. In 2003, Pevzner and Tesler argued against the random breakage model and proposed an alternative "fragile breakage" model of chromosome evolution. In 2004, Sankoff and Trinh argued against the fragile breakage model and raised...
متن کاملRole of DNA secondary structures in fragile site breakage along human chromosome 10.
The formation of alternative DNA secondary structures can result in DNA breakage leading to cancer and other diseases. Chromosomal fragile sites, which are regions of the genome that exhibit chromosomal breakage under conditions of mild replication stress, are predicted to form stable DNA secondary structures. DNA breakage at fragile sites is associated with regions that are deleted, amplified ...
متن کاملA small supernumerary marker chromosome, derived from chromosome 22, possibly associated with repeated spontaneous abortions.
We report a phenotypically normal couple with repeated spontaneous abortions and without other clinical features. Clinical, hematological, biochemical, and endocrinological aspects of the couple did not reveal any abnormalities. The karyotype of the wife was normal (46,XX), while the husband was found to have an abnormal karyotype, 47,XY,+der(22)mat. The marker chromosome was familial and non-s...
متن کاملChromosome breakage and repair.
FROM time to time one of my colleagues working at a medical school commiserates with me because I spend 40 hr a year lecturing to undergraduates. I always reply that teaching has compelled me to learn a lot of material that I would not have known about had I taught only my specialized subject. These forays into the ‘‘beyond’’ were instrumental in moving my research in new directions. Three arti...
متن کاملChromosome breakage and ultrasound.
Human lymphocyte cultures were examined for chromosome damage after exposure to ultrasound. Control and treated slides were scored "blind" and showed no evidence of damage due to ultrasound. Neither was there evidence of chromosome damage in blood cultures from six infants whose mothers had ultrasound during pregnancy when compared with that from six infants whose mothers had not. Our results s...
