title: The characterization of Euglena gracilis DNA by its reassociation kinetics.
abstract: The reassociation kinetics of Euglena gracilis DNA were carried out to determine the Cot 1/2 of the unique DNA (2000). The Cot 1/2 of the unique DNA and the amount of DNA per cell were used to show that this alga is not polyploid. Three kinetically definable classes of DNA were observed: a highly repetitive fraction, a middle repetitive fraction, and a non-repetitive fraction. Each fraction of DNA was characterized by its melting properties (Tm).
