Role of Ribosomes in Protein Synthesis | Genetics

Ribosomes involved in protein synthesis could lie free in the cytoplasm or are bound to membranes of endoplasmic reticulum. Free ribosomes synthesise protein without a signal sequence, and continue synthesis until the polypeptide is completed. Such a protein may assume its three-dimensional conformation with the help of chaperones present in the cytosol. Some of the important destinations for proteins synthesised [...]
