Polysome, Polyribosome

Polysome, Polyribosome - a structure of the cell cytoplasm, which consists of several ribosomes connected by messenger RNA molecules.

Polysomes are formed during the process of translation, when several ribosomes simultaneously read the coding sequence of one mRNA. Due to this, several copies of the same protein are synthesized simultaneously.

Polysomes can significantly speed up the process of protein biosynthesis in the cell. The longer the mRNA and the more ribosomes simultaneously translating its sequence, the larger the polysome and the more efficiently the protein encoded in it is synthesized.

Thus, polysomes play an important role in regulating gene expression levels at the posttranscriptional level. Their number and size reflect the intensity of the synthesis of certain proteins in the cell.

Polysome and polyribosome are structures of the cell cytoplasm that consist of several ribosomes interconnected by messenger RNA molecules. These structures play an important role in the process of protein synthesis in the cell.

Ribosomes are cellular organelles that synthesize proteins based on information contained in messenger RNA (mRNA). When mRNA leaves the cell nucleus and enters the cytoplasm, ribosomes begin to bind to its molecules and begin protein synthesis. However, for a protein to be synthesized efficiently, several ribosomes must be linked to each other on a single mRNA.

It is for this purpose that polysomes and polyribosomes serve. A polysome is a group of ribosomes linked together on a single mRNA that synthesize proteins simultaneously. A polyribosome is a more general concept that describes any number of ribosomes linked together on a single mRNA.

Binding multiple ribosomes on a single mRNA has several advantages. First, it allows the cell to synthesize proteins much faster than if each ribosome synthesized the protein separately. Second, the binding of ribosomes to a single mRNA allows the cell to use resources efficiently because the mRNA is reused to synthesize multiple proteins.

Polysomes and polyribosomes are important for cell biology and are key elements in the process of protein synthesis. Their study helps to deepen our understanding of the mechanisms underlying the life processes of cells and may lead to the development of new methods for treating various diseases associated with impaired protein synthesis.

Polysome and polyribosome in biology

Polysomes and polyrbosomes are structures of the cellular cytoplasm that consist of several rlbsomes linked to each other by messenger RNA (mntrime) molecules. Polysomones are formed during protein synthesis on ribosomes (rzbmoms) due to the connection of ribosomes of the matrix complex with ribosomes of the next level. Prodimones are three or more associated proteinsomes that can be found on the surface of a eukaryotic cell. They play an important role in the regulation of prnito-synthetic processes, since they control the amount of information, as well as synthesized proteins. In other words, polyresins influence protein synthesis and regulate their amount in the cell. Structure of polysystems
