What is the process of assembling proteins?

The process of assembling a protein from mRNA is called translation, and occurs in the ribosome.

What is responsible for assembly of proteins?

Ribosomes are cell organelles that consist of RNA and proteins. They are responsible for assembling the proteins of the cell. Depending on the protein production level of a particular cell, ribosomes may number in the millions.

Where does the assembly of a protein occur?

Ribosomes
Ribosomes are mostly constructed in the cell nucleus, but the final stages of assembly occur in the cytoplasm of the cell. A protein called Nmd3 binds to the partly constructed ribosome to export it out of the nucleus.

What transports proteins around the cell?

The Golgi apparatus
The Golgi apparatus transports and modifies proteins in eukaryotic cells.

What are amino acids held together by?

Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

What happens during the protein assembly line?

When new proteins are produced, they are deposited into cisternae on the ‘cis’ side of the Golgi. These proteins undergo a maturation process as they migrate toward the ‘trans’ side of the Golgi before being released into the cell as fully processed proteins (Fig. 1).

What is the assembly of proteins from amino acids?

To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.

How is protein transported?

From the endoplasmic reticulum, proteins are transported in vesicles to the Golgi apparatus, where they are further processed and sorted for transport to lysosomes, the plasma membrane, or secretion from the cell.

How are proteins made and transported?

The Golgi processes proteins made by the endoplasmic reticulum (ER) before sending them out to the cell. Proteins must make their way through the stack of intervening cisternae and along the way become modified and packaged for transport to various locations within the cell (Figure 1).
