                                Ribosomes of bacteria Introduction:   Proteins are the important components of living cells which contribute a lot in cellular activities. Despite the cellular type of organisms, every living cell requires proteins at a defined level to carry on their activities. Multi cellular organisms such as plants and animals cannot even imagine their life without proteins. Acellular organisms such as the viruses depend upon their host cell machinery to synthesize their proteins that are encoded by their genetic material. "Ribosome" is the main site of protein synthesis within a cell. Bacteria also contain ribosomes, which have different types of sub units when compared to those of the Eukaryotes.  Electron microscopy is a boon to the field of Science as it gave us the opportunity to view sub cellular components along with the atomic and sub atomic particles . Amino acids are the building blocks of proteins, which are linked to one another trough p

Bacterial Inclusions Introduction: Bacterial cells are simple and have very few organelles within them. Unlike the eukaryotes, The cytoplasm of the Bacteria is loaded with few organelles among which comes the inclusions, formed by the gathering of the organic or inorganic substances. These bodies have a different role and exist in different forms such as the granules, crystals, globules etc. Since bacteria survive in nutrient deprived areas, They need to store certain nutrients or inorganic molecules such as phosphate, sulfur etc which are the important for the formation of various cell organelles such as the nucleic acids, amino acids. Some inclusions are not for storage purpose and are involved in various other activities such as the Aquatic magnetotactic bacteria have magnetosomes that help in orienting these bacteria according to the magnetic field of the earth. Various inclusions identified within the bacteria are explained further in short as below. Storage inclusions
