Question

What is the role of ribosomes in protein synthesis?

Answer 1

1. Ribosomes are protein production sites.
2. A ribosome has one mRNA binding site and three tRNA binding sites. They are the P (peptidyl tRNA site), A (aminoacyl tRNA site), and E (exit site).
3. In eukaryotes, a groove located between two ribosomal subunits shields the polypeptide chain from the activity of cellular enzymes as well as mRNA from the action of nucleases.
