Ribosomes are discovered by

WebbRibosomes are found throughout the cell but are generally concentrated around the endoplasmic reticulum and the nuclear envelope. They can range from the thousands to the millions. The Endoplasmic Reticulum. The endoplasmic reticulum (ER) is a network of sacs and tubules that form a complex structure with internal space. Webb31 aug. 2024 · The initial clue that this RNA might function as a ribozyme was that the genes frequently found near to bacterial twister ribozymes are also commonly found nearby to bacterial hammerhead ribozymes . This similarity in associated genes suggested a similar function, a hypothesis that was confirmed experimentally ( 23 ).
