In this article we will discuss about the characteristics and examples of Cytoplasmic Inheritance. Characteristics of Cytoplasmic Inheritance: Information concerning cytoplasmic inheritance is meagre but whatever is known about the occurrence and action that is highly confusing. Some of the cytoplasm characteristics appear to be under the ultimate control of chromosomes but in other cases there is no evidence of [...]
In this article we will discuss about the Nucleus-Cytoplasm Interaction with Hammerling’s Experiment.

The cytoplasm provides the suitable environment in which the cytoplasmic as well as nuclear genes operate. Many enzymes operate through the cytoplasm and particularly through certain living cytoplasmic [...]
In this article we will discuss about the Streptomycin Resistance in Chlamydomonas. Ruthsagar (1965) has reported some cases of extrachromosomal inheritance in green alga chlamydomonas reinhardi. The alga reproduces by asexual as well as sexual means. It does not have different sexes but has positive and negative strains or mating types (mt+ and mt). The sexual reproduction involves fusion between [...]
