Question

kappa particles in paramecium

Answer 1

certain strains of the paramecium contain in their cytoplasm particles known as kappa particles .

Answer 2

Answer:

Kappa particles in paramecium are an example of cytoplasmic inheritance.

Explanation:

Kappa particles containing paramecium strains are called killer strains which were discovered in 1938. Kappa particles are about 2 micrometer in diameter containing DNA and protein. Kappa particle containing strains are able to secrete paramecin which can kill the sensitive strains. The nuclear dominant gene K is responsible for the presence of kappa particles in killer strains. Kappa particles are not true organelles but they are infectious and resembling caedobactor taeniospiralis bacteria. The toxic material produced by kappa particle does not affect the killer strain itself shown the due to the lack of membrane structure. Strains containing dominant homozygous K or heterozygous in their cytoplasm possess killer ability.
