In this article we will discuss about:- 1. Discovery of Ribosomes 2. Occurrence of Ribosomes 3. Functions. Discovery of Ribosomes: Ribosomes were discovered by Robinson and Brown (1953) in plant cells and by Palade (1955) in animal cells. Palade (1955) also coined the term of ribosome. A large number of ribosomes occur in a cell. For example, a single cell [...]
In this article we will discuss about the Structure and Functions of Centrioles. Structure of Centrioles: Centrioles are minute-sub-microscopic micro tubular sub cylinders with a configuration of nine triplet fibrils and ability to form their own duplicates, astral poles and basal bodies, without having DNA and a membranous covering. They are approximately 0.3-0.5 µm in length and 0.15µm in diameter. [...]
