Scientists Discover Enzymes Capable Of Duplicating Damaged Genetic Material And Creating New Mutations

Summary:
The key to life is the cell's ability to "compromise,” allowing DNA repair systems to operate with a certain "sloppiness" that permits a small number of mutations. While this may pose a certain risk, it also ensures the cell’s continued existence. Equally important, it increases genetic diversity allowing natural selection, the driving force behind evolution, to come into play. Prof. Zvi Livneh of the Weizmann Institute’s Biological Chemistry Department has discovered a group of enzymes that perform one such mechanism.

New York, NY--November 6, 2000 -- Genetic material (DNA) is damaged on a daily basis due to environmental factors, such as solar radiation and exposure to certain hazardous materials, as well as natural cell processes. This damage can leave chaos in its wake, scrambling or deleting the genetic “letters” encoding an organism’s traits. If left unchecked, the mutated DNA will continue to replicate, and may cause impaired protein production and disease.
