Why are nucleus and nucleolus structures important?
We can call the nucleus as the control center because it contains the DNA or the deoxyribonucleic acid. This DNA is like a blue print that contains all the intructions needed for building the whole body; like for building proteins, cell reproduction etc. Within this nucleus are three regions these are the nuclear envelope, nucleoli and chromatin. Nucleoli are the sites where the ribosomes are made. Nucleoli is important because these ribosomes are very important for protein synthesis.
