How do ribosomes get to the ER from the nucleus?
A ribosome contains RNA and proteins. The following description applies to eukaryotes (plants, animals, and fungi). (The ribosomes of prokaryotes (bacteria) and mitochondria are essentially similar but differ in detail, and no nucleus is involved.) A ribosome in eukaryotes, including humans, contains four different molecules of rRNA (ribosomal RNA) and about 80 protein molecules. The proteins are synthesized in the cytoplasm, then transported through nuclear pores into the nucleus. The rRNA molecules are synthesized directly from genes in the nucleus. The nucleolus is a region of the nucleus in which three of these rRNA genes occur. Inside the nucleus the RNA and protein molecules are assembled into two subunits, which leave the nucleus, again through nuclear pore complexes. Once in the cytoplasm, the two subunits are combined to form the functional ribosome.
Where rRNA is formed?
Ribosomal RNA or rRNA is synthesized in a specialized region of the cell nucleus called the nucleolus. It is made through the process of transcription.
What is The small body in the nucleus that assembles ribosomes is called?
The nucleolus is the small dense region in the nucleus where the assembly of ribosomes begin. It makes up 25 percent volume of the cell nucleus and its malfunction may cause diseases in the human body.
What has an dark round structure within the nucleus that produces ribosomes?
I think what you're asking for is the nucleolus, the darker area of the nucleus that contains the DNA used to code ribosomal RNA.The dark circle in the nucleus is the nucleolus/nucleole (it's called both.)It's comprised of densely packed chromatin, and is where rRNA is transcribed before exiting the nucleus.
What cell organelle is made in the nucleus in a special area called the nucleolus?
The nucleolus contains the instructions for creating ribosomes (rRNA).
What is the body within the nucleus that is the site of ribosomal-RNA synthesis?
The nucleolus is the site inside the nucleus where rRNA synthesis occurs.
Are ribosomes made in a special region of the nucleus called the nucleolus?
Ribosomes are made inside the nucleolus, which is inside the nucleus of the cell. Ribosomes function to synthesize proteins. ***************************** it controls which qenes qet used.
How is the nucleolus important?
The nucleolus, the largest formation inside a nucleus, is responsible for the creation of RNA, which along with DNA and proteins from the basis of all life. Furthermore, the nucleolus regulates the movement of RNA from the nucleus to the cell cytoplasm.
Are found inside the nucleus of the cell?
Nucleus consist of : chromosomes- present as extended nucleoprotien fibers called chromatin nuclear matrix- which is a protine containing fibrillar network nucleolus- that are responsible for synthesis of rRNA and assembling of ribosoms nucleoplasm- the fluid substance in which the solutes of nucleus are dissolved

Does a nucleus contain functional ribosomes?
yes the nucleolus, which is locate din the nucleus contain ribosomes and ribosomal RNA (rRNA)
What is the dark circle in the nucleus?
In most pictures, it is the nucleolus. It is called the nucleolus.
How does the nucleus and the ribosome work together?
Nucleolus are sites of ribosomal ribonucleic acid (rRNA) synthesis.
Where rRNA is formed?
Ribosomal RNA or rRNA is synthesized in a specialized region of the cell nucleus called the nucleolus. It is made through the process of transcription.
What organelle contains RNA?
It can either be: ribosome, where the tRNA, rRNA, and mRNA meet to translate the message into proteins, or it can also be nucleolus, where the rRNA is being transcribed, or it can also be found in the nucleus, where the mRNA is being transcribed.
What is The small body in the nucleus that assembles ribosomes is called?
The nucleolus is the small dense region in the nucleus where the assembly of ribosomes begin. It makes up 25 percent volume of the cell nucleus and its malfunction may cause diseases in the human body.
What is the function of the what is the function of Nucleolus?
rRNA is transcribed (and assembled) inside the nucleolus.
