Ribosome in the cell

WebbRibosomes are comprised of proteins and ribosomal RNA (rRNA) and are found in all organisms because they are the cellular sites for protein synthesis. Presently, the genes coding for rRNA are used most extensively to obtain phylogenetic information. Webb24 maj 2024 · Ribosome biogenesis is a complex and energy-demanding process requiring tight coordination of ribosomal RNA (rRNA) and ribosomal protein (RP) production. Given the extremely high level of RP synthesis in rapidly growing cells, alteration of any step in the ribosome assembly process may impact growth by leading to proteotoxic stress.
