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). A polyribosome (or polysome or ergosome) is a group of ribosomes bound to an mRNA molecule like “beads” on a “thread”.
