Illustration of a Ribosome

noun

The definition of a ribosome is a tiny particle made up of nucleic acids and proteins that exist in large numbers in the gel-like substance in between every cell in the body.

Facts About Ribosome

Ribosome gets its name from "ribonucleoprotein particles" and "microsomes" which are both particles inside the cell. Richard B. Roberts suggested "ribosome" in 1958.
In 1955, George Palade, a cell biologist, along with Philip Siekevitz, discovered ribosomes and identified their function as making proteins.
Ribosome refers to ribonucleoprotein particles in sizes ranging from 35 to 100S.

An example of a ribosome is one of the particles located outside of a cell that helps build proteins.

A sphere-shaped structure within the cytoplasm of a cell that is composed of RNA and protein and is the site of protein synthesis. Ribosomes are free in the cytoplasm and often attached to the membrane of the endoplasmic reticulum. Ribosomes exist in both eukaryotic and prokaryotic cells. Plastids and mitochondria in eukaryotic cells have smaller ribosomes similar to those of prokaryotes.
