Preservation of Cultures in an Organism

A pure culture of an organism is a valuable asset and it deserves to be preserved for future. Normally, the cultures which are of daily use are grown in agar slants and kept in the refrigerator. When required, a loopful of growth is transferred to fresh agar or broth and the organisms are allowed to grow in an incubator. For [...]

Molecular Structure of Proteins (With Diagram) | Metabolism

In this article we will discuss about the molecular structure of proteins with the help of diagrams. Quantitatively, proteins are the chief organic components of most living organisms, as also of viruses. About 50% of the dry weight of bacterial cells is protein. The flagella, pili and fimbriae are made up entirely of proteins, and the cell membrane, cytoplasm, ribosomes [...]
