Isolation and characterization of the mitochondrial DNA from the florida spiny lobster, Panulirus argus

1. Mitochondria and mitochondrial DNA were isolated from the digestive gland of Panulirus argus. 2. The mitochondrial DNA has an average contour length of 5.13 microns which corresponds to a molecular weight of 10.10 X 10(6) daltons. 3. The molecular weight based on agarose gel electrophoresis of restricted individual DNA samples ranges from 10.04 to 10.4 X 10(6) daltons. 4. Restriction endonuclease analysis with Bam H1 and Eco R1 demonstrate variation in nucleotide sequence between individual lobsters.
