    In biology, a taxon is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established

    A cellular nucleus is a dense region with definite boundaries present in the cytoplasm of a cell which is responsible for all kinds of metabolic activities occuring inside the cell. Though it was discovered as a cell organelle in 1831 by Robert Brown, it was later found that there was a factor which made it so important than other organelles - a CHROMATIN thread which consists of a 2 m long ? strand bound around mostly Histone (and a few non-histone) proteins.
