Role of ribosomes?
Basically, the role of ribosomes is to make proteins. Normally, there are two parts of ribosome which come together when translation occurs. When a mRNA comes into the cytoplasm, ribosome will attach itself to the mRNA and make polypeptide chains. It then releases the mRNA and the polypeptide, then the polypeptide goes through further enhancement to become a fully functional protein.
What Proteins are synthesized?
During protein synthesis, or translation, is a process that uses a messenger RNA transcript that is translated by a ribosome. Charged tRNAs carry new amino acids to the ribosome-mRNA complex. These amino acids are added to a growing polypeptide chain, with each amino acid being specifically added based on a three-nucleotide base mRNA codon-tRNA anticodon association.
What process takes place in the Ribosome?
Ribosomes are the site of protein synthesis. This is where mRNA is read and a sequence of amino acids are joined together to form a polypeptide/protein.
Is the ribosome in the nucleus?
Ribosomes are synthesized in the nucleolus by combining rRNA which is made there and ribosomal proteins that are synthesized in the cytoplasm and are imported into the nucleus. The ribosome is exported out of the nucleus and into the cytoplasm or are deposited on the rough ER. Ribosomes do not become fully active until they leave the nucleus.
How does prokaryotic cells secrete proteins?
Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane.

What happens to ribosomes during protein synthesis?
Protein synthesis take place on ribosomes.They provide surface for it.

What is the job for ribosome?
They synthesize proteins in cell.They provide surface for that
What is produced in the ribosome?
Proteins are produced in ribosomes.Ribosomes give surface for it
How does prokaryotic cells secrete proteins?
Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane.
The receptors for catecholamine and polypeptide hormones are found?
on the outer surface of the target cell
What ER with ribosome attached to its surface?
Rough endoplasmic reticulum (RER)
Which cell organelle puts amino acids together in a specific order to make proteins?
This would be the function of the ribosomes. The ribosome assembles amino acids into proteins. Ribosomes are small structures made of ribosomal RNA (rRNA) and protein. (RNA is a molecule similar in structure to DNA.) When cells need to make proteins, they copy the instructions for the protein from the DNA of the cell by making a molecule of messenger RNA (mRNA). The mRNA travels to the ribosomes in the cytoplasm of the cell. Another type of RNA molecule, called transfer RNA (tRNA) brings amino acids to the ribosome. The tRNA molecules decode the mRNA by binding to it, so that the tRNAs bring in the correct amino acids according to the instructions in the mRNA. The ribosome helps keep this whole process organized and helps form the bonds between the amino acids to create a chain of amino acids. A chain of amino acids is called a polypeptide chain. Polypeptide chains fold up to form proteins.
What is thefunction of a ribosome?
They provide surface for protein synthesis.They are sites of protein synthesis
