The ability to photorepair UV damaged DNA and the rate of photoreactivation in Antarctic species compared with temperate and tropical species
Entry ID: K068_2004_2006_NZ_2

Abstract: Time course experimental exposure of the Antarctic sea urchin Sterechinus neumayeriembryos to UVR was carried out in a lab to examine the kinetics of UVR induced damage to DNA. Embryos (freshly fertilized embryos, blastula and 4 armed larvae) were exposed to artificial light with samples taken at 0, 1, 2, 6, 12 and 24 hours post exposure. Cyclobutane pyrimidine dimers (CPDs) were quantified. To ... View entire text
