What is the function of the nucleus and nucleolus?

What is the function of the nucleus and nucleolus?

The nucleolus is a structure found in the nucleus of cells and it forms around specific chromosomal regions in the nucleus of eukaryotic cells, and is made up of proteins and ribonucleic acids. Its main function is to transcribe ribosomal RNA (rRNA) and combine it with proteins to form incomplete ribosomes.

Is DNA in the nucleolus or nucleus?

The nucleus of a eukaryotic cell contains the DNA, the genetic material of the cell. … The nucleolus is the central portion of the cell nucleus and is composed of ribosomal RNA, proteins and DNA. It also contains ribosomes in various stages of synthesis. The nucleolus accomplishes the manufacture of the ribosomes.

Does the nucleus protect the nucleolus?

The envelope protects the nucleus from the rest of the cytoplasm in the cell and keeps the special molecules within the nucleus from getting out. Nucleolus – The nucleolus is a large structure in the nucleus that mainly makes ribosomes and RNA. … They organize into chromosomes prior to the cell dividing.

Which is more important nucleus or nucleolus?

The nucleus is the most important organelle in the cell. … The nucleolus within the nucleus is the site for RNA synthesis as well as DNA replication.
