WebThe job of the ribosome is to make new proteins. It does this by moving along a strand of messenger RNA and building a protein based on the code it reads. Making a protein this way is called translation. We need up to 10 million robots (ribosomes) in every cell. To get this number, cells have many copies of rRNA genes. WebStep 1: Definition of ribosome The protein synthesis takes place in a site called a ribosome. These are cell organelles found attached to the endoplasmic reticulum and consist of RNA along with protein. They are small, circular-shaped organelles in appearance. Step 2: Transfer of genetic instruction
