Mitochondrial DNA from Lumbriculus variegatus: Isolation and Restriction Digest Analysis
In this activity, mitochondria are isolated from the California blackworm, Lumbriculus variegatus, by homogenization and differential centrifugation. A modified plasmid miniprep procedure (alkaline lysis) is then used to isolate DNA from these mitochondria. Single and double enzyme restriction digests of mitochondrial DNA (mtDNA) are analyzed by agarose gel electrophoresis. Sizes of mtDNA restriction fragments are estimated from gel results and are used to determine the total size of the L. vari

Erythemal Index for August 2000 through July 2001: Slow Rotating Globe
The Erythemal Index is a measure of ultraviolet radiation (UV) at ground level on the Earth. UV exists to the left of the visible spectrum and is divided into three components (UV-A, UV-B and UV-C). UV-B (290-320 wavelengths) is the most dangerous form of UV radiation that can reach ground level. Atmospheric ozone shields life at the surface from most of the harmful components of solar radiation. Chemical processes in the atmosphere can effect the level of protection provided by the ozone in the
