A model organism is a species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. This is possible because fundamental biological principles such as metabolic, regulatory, and developmental pathways, and the genes that code for them, are conserved through evolution.
Often, model organisms are chosen on the basis that they are amenable to experimental manipulation. This usually will include characteristics such as; short life-cycle, techniques for genetic manipulation (inbred strains, stem cell lines, and transfection systems), and non-specialist living requirements. Sometimes, the genome arrangement facilitates the sequencing of the model organism's genome, for example, by being very compact or having a low proportion of junk DNA.
There are many model organisms. One of the first model systems for molecular biology was the bacterium Escherichia coli a common constituent of the human digestive system. Several of the bacterial viruses (bacteriophage) that infect E. coli also have been very useful, for example phages Lambda and T4.
