WebbRibosome formation is a highly dynamic and coordinated multistep process, which requires synthesis, processing and modification of pre-rRNAs, assembly with ribosomal proteins and transient interaction of numerous non-ribosomal factors with the evolving pre-ribosomal particles. WebbA ribosome is a complex macromolecule composed of structural and catalytic rRNAs, and many distinct polypeptides. In eukaryotes, the nucleolus is completely specialized for the synthesis and assembly of rRNAs. Ribosomes exist in the cytoplasm in prokaryotes and in the cytoplasm and rough endoplasmic reticulum in eukaryotes.
