The nucleus is the most important eukaryotic organelle for a cell. All living systems contain ribosomes and all organisms do require protein. The nucleus itself contains nucleoli which are large bodies that have special regions of clump together DNA. The DNA which is clumped together make small spherical organelles known as the city’s factory or ribosome RNA. Guided by the message from the nucleus via DNA ribosomal RNA directs the production of protein. Without the nucleus telling the different parts of the cell what to do and when to do it there would be chaos. The food and water would not be stored, the trash would not be taken out, protein would not be produced, and the police force would not know which incident they need to check out first.
