Abstract
The mitochondrial DNA from pea leaves exists in a circular conformation. 25% of the circular molecules exist as supercoils, and 10% of the molecules are dimers. The molecular weight of mitochondrial DNA is about 66 to 70 x 10(6) by electron microscopy, and 74 x 10(6) from its renaturation kinetics. No evidence for inter- and intramolecular heterogeneity is found.Keywords
