Nucleoli are structures found within the nucleus of eukaryotic cells, primarily responsible for the production and assembly of ribosomal RNA (rRNA) and ribosomal subunits. They play a crucial role in ribosome biogenesis, which is essential for protein synthesis in the cell. Additionally, nucleoli are involved in the processing of rRNA and the incorporation of ribosomal proteins to form functional ribosomes. Their activity can vary based on the cell's metabolic state and developmental stage.
What else can I help you with?
How many nucleoli are in each nucleus?
Typically, a nucleus contains one or more nucleoli. The number of nucleoli can vary depending on the cell type and its activity. Nucleoli are involved in the production of ribosomes and are often more numerous in cells actively synthesizing proteins.
What are cells without nucleoli called?
Cells without nucleoli are termed anucleolate cells. This absence of nucleoli can be due to certain cellular conditions or can be a natural feature of the specific cell type. Nucleoli are responsible for producing ribosomal RNA and are important for protein synthesis within the cell.
Where are the nucleoli of an onion cell found?
The nucleoli of an onion cell are found within the nucleus. The nucleus is a membrane-bound organelle that houses the cell's genetic material, including the nucleoli where ribosomal RNA synthesis takes place.
Does a cell that secretes abundant proteins have many nucleoli?
Potentially in some organisms, but generally protein production correlates with nucleolus size rather than number. For example, the number of nucleoli in humans in fixed; there is one per diploid cell. Muscle cells would have larger nucleoli, but not more of them. The reason for this is because the nucleolus produces rRNA, a component of ribosomes, which synthesizes protein.
Is nucleoli in plant or animal cell?
A nucleolus is in both plants and animals.
What is the plural of nucleoli?
Nucleoli is the plural form of nucleolus.
In an animal cell what contains DNA and nucleoli?
The nucleus of the cell contains DNA and the nucleoli.
Dense area of nucleus?
Within the nucleus are one or more dense regions called nucleoli. Their function is to synthesize ribosomal RNA and assemble ribosomes.
How many nucleoli are in each nucleus?
Typically, a nucleus contains one or more nucleoli. The number of nucleoli can vary depending on the cell type and its activity. Nucleoli are involved in the production of ribosomes and are often more numerous in cells actively synthesizing proteins.
What are cells without nucleoli called?
Cells without nucleoli are termed anucleolate cells. This absence of nucleoli can be due to certain cellular conditions or can be a natural feature of the specific cell type. Nucleoli are responsible for producing ribosomal RNA and are important for protein synthesis within the cell.
What does a neucleolus do?
Nucleoli assemble ribosomes.
Do epithelial cell have nucleoli?
yes it have.
What is assembled in the nucleoli?
The nucleus of a cell contains the genetic material, so for proteins to be made, the cell makes a copy of the DNA in RNA and that is brought out of the nucleus, so it could be said that the nucleus makes RNA. Also, during cell division, the DNA is copied within the nucleus, so it could be said that the nucleus makes DNA as well.
Where are the nucleoli of an onion cell found?
The nucleoli of an onion cell are found within the nucleus. The nucleus is a membrane-bound organelle that houses the cell's genetic material, including the nucleoli where ribosomal RNA synthesis takes place.

Does nucleoli have their own distinct membranes?
No, nucleoli do not have their own distinct membranes. They are found inside the nucleus of a cell and are composed of proteins and ribonucleic acids. Nucleoli are involved in the production of ribosomal RNA and assembly of ribosomes.
What is oval shaped bodies found inside the nucleus of most cells?
Oval shaped bodies found inside the nucleus of most cells are called nucleoli. Nucleoli are involved in the production of ribosomes, which are essential for protein synthesis in the cell.
