A polyribosome (or polysome or ergosome) is a group of ribosomes bound to an mRNA molecule like "beads" on a "thread". [1] It consists of a complex of an mRNA molecule and two or more …

Jun 14, 2025 · What Is a Polysome? A polysome is a string of messenger RNA (mRNA) molecules simultaneously occupied by multiple ribosomes. Each ribosome on the mRNA …

Polysomy is usually caused by non-disjunction (the failure of a pair of homologous chromosomes to separate) during meiosis, but may also be due to a translocation mutation (a chromosome …

When multiple ribosomes attach to a single mRNA molecule and simultaneously translate it, they form a structure called a polysome, also known as a polyribosome. These polysomes …

Polysomes composed of 2 ribosomes travel further, polysomes with 3 ribosomes travel further still, and on and on. The "size" of the components is designated by S, the svedberg unit. Note …

Un polysome ou polyribosome est un ensemble de ribosomes reliés entre eux par un ARN messager 1. Cet ensemble a l'aspect d'un collier de perles. Ils sont le lieu de la biosynthèse …

A polysome, also known as a polyribosome, is a complex formed by multiple ribosomes simultaneously translating a single mRNA strand. This structure allows for the efficient …

Jul 25, 2024 · Cellular stress responses almost universally lead to inhibition of translation, resulting in polysome collapse and release of mRNA. The released mRNA molecules …

Mar 14, 2025 · Here, we demonstrate the versatility of polysome profiling—a methodology traditionally used to assess levels of protein synthesis—to monitor ribosomal integrity and …

Apr 30, 2025 · Here, we present a protocol for polysome profiling in differentiating adipocytes from the mouse stromal vascular fraction. We describe steps for lysate preparation, …
