Webpolyribosomes. To determine whether ICP27 protein is asso-ciated with the translation machinery in HSV-1-infected cells, sucrose gradient analysis was used to separate polyribosomes from monoribosomes and uncomplexed ribosomal subunits. BHK-21 cells were either mock infected or infected with wt virus or the ICP27 mutant M15, carrying … WebDifferential accumulation of host mRNAs on polyribosomes during obligate pathogen-plant interactions.

WebWhat do polyribosomes do? Polyribosomes attached to the endoplasmic reticulum synthesize proteins for export from the cell (e.g., digestive enzymes) and for placement … A polyribosome (or polysome or ergosome) is a group of ribosomes bound to an mRNA molecule like “beads” on a “thread”. It consists of a complex of an mRNA molecule and two or more ribosomes that act to translate mRNA instructions into polypeptides. Originally coined "ergosomes" in 1963, they were … See more Electron microscopy technologies such as staining, metal shadowing, and ultra-thin cell sections were the original methods to determine polysome structure. The development of cryo-electron microscopy techniques has … See more Polysomal Profiling is a technique that uses cycloheximide to arrest translation and a sucrose gradient to separate the resulting cell extract … See more • Theoretical and experimental structure of polysome See more fm Joseph\u0027s-coat
