Functions of Nucleolus
The nucleolus is involved in the transcription of DNA into rRNA. rRNA further forms ribosomes. Thus, Nucleolus helps in ribosome biogenesis.
There are three types of RNA Polymerases for different types of rRNA.
- RNA Polymerase I forms 28S, 18S, and 5.8S rRNA
- RNA Polymerase II forms ribosomal protein
- RNA Polymerase III forms 5S rRNA.
Ribosomal proteins and rRNA get assembled to form subunits of ribosomes.
Nucleolus helps in nuclear detention which means capturing and immobilising proteins. It also helps in assembling the signal recognition particles.
Difference Between Nucleus and Nucleolus
Difference Between Nucleus and Nucleolus: Nucleus and Nucleolus are present inside eukaryotic cells. The main difference between nucleus and nucleolus is that nucleus is an organelle present in the cell and is bounded by a nuclear envelope whereas nucleolus is a sub-organelle present inside the nucleus and is not bounded by any membrane.
