Polysome theory
WebPolysomes: A rosette or helical cluster of ribosomes is brought together by a strand of messenger RNA to form a polysome (mRNA). They include a piece of the genetic code that is translated by each ribosome and are employed in the synthesis of numerous copies of the same polypeptide. It can be found in the cytoplasm or the endoplasmic reticulum. WebJan 9, 2024 · Polysome fractions are collected, and the abundance of mRNA in each fraction is measured by DNA microarray hybridization or RNA sequencing (RNAseq) (Fig. 4a). Translational control is determined by the change in the number of ribosomes loaded per mRNA that is defined as translation efficiency (TE) of the mRNA (Chikashige et al. 2024).
