Cytoplasmic Inheritance of Kappa Particles in Paramecium

In this article we will discuss about the Cytoplasmic Inheritance of Kappa Particles in Paramecium. One of the most striking and spectacular cases of cytoplasmic inheritance occurs in paramecium aurelia. In 1938, T.M. Sonneborn reported that some strains contain kappa particles in the cytoplasm and are known as "Killers ". Kappa particles are about 2 μ x in diameter and [...]

Paramecium: Origin, Particles and Reproduction

In this article we will discuss about:- 1. Subject-Matter of Paramecium 2. Reproduction and Mode of Action of Paramecium 3. Origin of Paramecium. Subject-Matter of Paramecium: Sonneborn in 1943 found that Paramecium aurelia strains could be classified into "Killer" and "Sensitive" types. The killer strain secreted a toxic substance "paramecin" in the growing medium and this toxin was responsible for [...]
