Summary Introduction
Introduction:
The binding sites that present in the ribosomes where the t-RNA molecules are attached are termed as points. These points are found in between the two subunits of the ribosomes. There are three types of points present in the ribosomal subunits namely: A (aminoacyl or acceptor), P (peptidyl), E (exit) sites.
