WebPolysome. In the cell, some polysomes are associated with the endoplasmic reticulum (presumably synthesizing secreted proteins, mitochondrial proteins, and proteins embedded in the membrane) while others remain as free polysomes, which are believed to synthesize proteins that will remain in the cytoplasm or move into the nucleus. WebMuch of the complexity of this process evolved on the eukaryotic lineage by the duplication of ribosomal proteins and their subsequent functional diversification into ribosome biogenesis factors. This highlights that studying ribosome biogenesis in archaea provides fundamental information also for understanding the process in eukaryotes.
