Web7 apr. 2024 · Nucleolus is a region within the nucleus made of ribosomal RNA (rRNA) and proteins. It is not delimited by membrane. WebNucleoli are made of protein and ribosomal DNA (rDNA) sequences of chromosomes. The rDNA is a fundamental component since it serves as the template for transcription of the ribosomal RNA (rRNA) for inclusion in new ribosomes. Most plant and animal cells have one or more nucleoli, but some cell types do not have any.
