Operon model was proposed by Francois Jacob and Jacques Monod.The operons are the genes that are coded for related protein. Operon consists of a regulator, promoter and the structural genes. Eukaryotic DNA has one operon for one gene that encodes only one protein. Prokaryotic DNA may have one operon for one or more protein as they have small DNA. They may encode two or three protein from the same promoter.
Fastidious bacteria are those that live on complex nutrition and need a special requirement for their growth. They have many other factors to grow properly.

Some bacteria produce heat- sensitive toxins that are destroyed by cooking. Even small fluctuations in temperature, toxins protein denatures and breaks. When toxins protein chain breaks, it’s function loss. It is unable to produce the disease.
Acid-fast bacteria are those bacteria that have mycolic acid in their cell wall. These bacteria stain acid-fast positive. This bacterium was first discovered...
