The following points highlight the five main classes of chemical compounds in chromatin. The classes are: 1. Nucleic acids 2. Basic proteins or histones (protamines in sperm nuclei of some fishes and birds) 3. Acidic proteins (Non-Histones) 4. Lipoproteins 5. Associated inorganic molecules. Chemical Compounds in Chromatin: Class # 1. Nucleic Acids: The nucleic acids are of two types: (i) [...]

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 [...]
