Representative agarose gel used in densitometric analysis of DNA recovery from spores irradiated with varying doses of EB radiation: lane 1, 1 kB Plus DNA Ladder; lane 2, nonirradiated spore DNA; lane 3, DNA from spores irradiated with 5.3 kGy; lane 4, DNA from spores irradiated with 10.4 kGy; lane 5, DNA from spores irradiated with 16.0 kGy; lane 6, DNA from spores irradiated with 21.7 kGy.
