Description of a ribosome structure
WebThe enzyme is a "synthetase" because it creates a new structure called "aminoacyl-tRNA", which is the tRNA which has an amino acid linked to it. The word "aminoacyl" means that an amino acid is linked to something, in this case tRNA. This process happens BEFORE the tRNA enters the ribosome and it takes place in the cytosol. WebThe structures of ribosomes include: Situated in two areas of the cytoplasm. Scattered in the cytoplasm and a few are connected to the endoplasmic reticulum. Whenever joined to the ER they are called the …
