Nucleus

	Nucleus - In the eucaryotic cell, the genetic material is stored in chromosomes (within the Nucleus) although mitochondria and chloroplasts also contain characteristic DNA. The chromosomes are distinct thread like structures mainly containing deoxyribonucleic acid (DNA) and basic proteins such as histones.
The size and the number of the chromosome vary widely with different organisms. The nucleus also contains a nucleolus which is associated with a specific chromosomal region known as the nucleolar organizer and is presumed to be involved in ribosomal RNA (r-RNA) synthesis
