Purpose

The ribosomes translate RNA into proteins.

Function

The ribosomes are small organelles attached to the endoplasmic reticulum. They take the RNA, which is a series of instructions from the nucleus, and translates them into proteins, which are instructions that the cell can understand. They are very small, only about 10 nano-meters (smaller than most viruses).

Location

The ribosomes are attached to the endoplasmic reticulum.
