Christopher J Chetsanga (born 1935 in Murehwa, Rhodesia) is a preeminent Zimbabwean scientist who is a member of the African Academy of Sciences. [3]
Education
- 1965 obtained a BSc degree at the University of California, Berkeley and Pepperdine University in California, USA[4]
- 1965-1969 obtained MSc and PhD degrees in Biochemistry and Molecular Biology at the University of Toronto, Canada[4]
- 1969-1972 became a Post-doctoral Fellow, Department of Biochemistry and Molecular Biology at Harvard University[5]
Scientific Achievements
Discovered two enzymes involved in the repair of damaged DNA:
- Formamidopyrimidine DNA Glycosylase, which removes damaged 7-methylguanine from DNA (1979).[6]
- DNA cyclase, which recloses imidazole rings of guanine and adenine damaged by x-irradiation (1985).[7]
