How does ribosomes reproduce?
Ribosomes are not able to reproduce on their own. They are produced in the nucleolus of a cell, a specialized region within the nucleus, where ribosomal RNA (rRNA) is synthesized and combines with proteins to form ribosomes. The newly formed ribosomes are then exported to the cytoplasm where they can participate in protein synthesis.
What is purpose of ribosomes?
Ribosomes are responsible for protein synthesis in the cell. They read the messenger RNA (mRNA) and assemble amino acids into polypeptide chains to create proteins. They are essential for the growth, development, and maintenance of all living organisms.
Do ribosomes become RNA after they enter the nucleus?
No, ribosomes do not become RNA (but they do contain RNA) and they do not enter the nucleus. mRNA travels from the nucleus to the ribosomes, which are found in the cytoplasm or on the outside of the rough endoplasmic reticulum (RER). The ribosomes do not enter the nucleus. Ribosomes contain a type of RNA called ribosomal RNA (rRNA) as well as protein.
What organelle come from nucleus to make proteins?
Ribosomes, which are the organelles responsible for synthesizing proteins, can be found either freely floating in the cytoplasm or attached to the endoplasmic reticulum. They are formed in the nucleolus inside the nucleus and then migrate to the cytoplasm to carry out protein synthesis.
This region inside a nucleus is where rRNA is produce?
The nucleolus is the region inside a nucleus where ribosomal RNA (rRNA) is produced. It plays a crucial role in the assembly of ribosomes, which are the cellular machinery responsible for protein synthesis.
How does mRNA enter the nucleus?
mRNA does not enter the nucleus. It is transcribed from DNA inside the nucleus and then exits the nucleus to carry genetic information to the ribosomes in the cytoplasm for protein synthesis.
What does the necleolus in a cell do?
The nucleolus is a region within the cell nucleus that is involved in ribosome synthesis. It helps in assembling ribosomal subunits from RNA and proteins. Ribosomes are essential for protein synthesis in the cell.
Creates ribosomes found inside the nucleus?
In eukaryotic cells, they are formed most often in the nucleolus. In eukaryotes, the ribosomes may be classified as either 'free' or 'bound'. Free ribosomes may be found suspended in the cytosol whereas bound ribosomes are attached to endoplasmic reticulum (as such called rough endoplasmic reticulum). Free ribosomes are involved in the synthesis of proteins that will function in the cytosol while bound ribosomes in the synthesis of proteins that are to be exported or used within the cell membrane. The two types of ribosomes have similar function and structure, and in fact, are interchangeable.
What organelle inside the nucleus makes ribosomes?
The structure is called nucleolus and it makes the two parts of ribosomes. It is numbered between one and three in a typical cell.
The site of protein synthesis?
Protein synthesis primarily occurs in the cytoplasm of a cell, specifically on ribosomes. These ribosomes can be free-floating or attached to the endoplasmic reticulum. The process involves translating the genetic information from mRNA into a specific sequence of amino acids to build a protein.

They are produced in the nucleolus of a cell, a specialized region within the nucleus, where ribosomal RNA (rRNA) is synthesized and combines with proteins to form ribosomes.

The nucleolus is responsible for producing ribosomal RNA (rRNA) and assembling ribosomes, which are essential for protein synthesis in the cell. It is found inside the nucleus and plays a crucial role in protein production.

The nucleolus is the region inside a nucleus where ribosomal RNA (rRNA) is produced. It plays a crucial role in the assembly of ribosomes, which are the cellular machinery responsible for protein synthesis.
What is the small dot-like structure inside the nucleus?
The small dot-like structure inside the nucleus is the nucleolus. It is responsible for producing ribosomes, which are essential for protein synthesis. The nucleolus is not surrounded by a membrane and can often be seen as a distinct structure within the nucleus.
