What are Ribosomes?
Ribosomes were first observed by George Palade (1953) under the electron microscope. It is a kind of complex molecular machine that produce proteins from amino acids during a process of protein synthesis also called translation. Ribosome translates genetic information stored in messenger RNA into proteins.
The process occur in three stages: initiation, elongation and termination. Within ribosomes, ribosomal RNA (rRNA) catalyzes the peptidyl transferase reaction, to form peptide bonds between amino acids, enabling them to form proteins. After protein is formed in the ribosome, they move to different areas of the cell for various cellular functions.
Ribosomes
Ribosomes are tiny, granular organelles found in both eukaryotic and prokaryotic cells. They are found inside the cytosol of the cell. Ribosomes are the site of protein synthesis. They translate the genetic information conveyed by messenger RNA (mRNA) into functional proteins.
Ribosomes are composed of two subunits, one larger and one smaller, each of which is made up of proteins and RNA molecules. In this article, we will cover the ribosome structure and function, diagram, and more.
