                                   Five Kingdom Classification Early biologists classified all species as either plants or animals. Since this method makes it difficult to research specific creatures, American taxonomist R.H. Whittaker created the five-kingdom classification in 1969. This system divides all organisms into groups based on how they are organized and how they are fed. Important standards for this classification include - The complexity of cell structure i.e. Prokaryotic and Eukaryotic. The complexity of the Organisms body is Unicellular and Multicellular. Mode of nutrition Autotrophs and Heterotrophs. Lifestyle. Phylogenetic Relationship. Based on these criteria, Whittaker classified the living world into the following categories  - Kingdom Monera                 Kingdom Protista Kingdom Fungi Kingdom Animalia Ki...

                                 Recombinant DNA Technology The technology in which genetic material   is transferred by artificially means from one organisms to genome of another organisms where it replicate and expressed is  called Recombinant  DNA Technology . For Example - The best example to understand this process is Mosquito . Mosquito act as a vector and transfer it's pathogen into human body where it replicate and expressed in form of disease called Fever , Dengue , Malaria etc . Tools Of   rDNA Technology - rDNA technology accomplish only  by  using this key tools -                                                        Restriction Enzyme        Polymerase Enzyme       ...
