Summary Introduction
Introduction:
There are three domains of life as Bacteria, Archaea and Eukarya. Bacteria and Archaea are unicellular organisms and Eukarya contains palnts, animals, fungi and protists. Bacteria and Archaea are altogether named as prokaryotes because they lack a nucleus, but they have nuclear materials in the cytoplasm like, plasmids.
