Can nucleolus be found in prokaryotes
WebThe nucleolus is a smaller organelle found within the nucleus of eukaryotic cells. The nucleolus is comprised of collections of DNA, RNA, and various proteins. The components that make up the nucleolus are gathered around areas known as nucleolus or organizing regions. The nucleolus doesn't just organize RNA and DNA, it also serves as the
