Fence Creek Publishing, 1999.) The basic unit of heredity is the gene, a segment of deoxyribonucleic acid ( DNA) that encodes in its nucleotide sequence information for a specific physiologic property. Amplification of specific regions of DNA also can be achieved with bacterial enzymes using polymerase chain reaction (PCR) or other enzyme-based method of nucleic acid amplification. This involves both discovering the regulatory genes and sites that control individual gene expression and determining which genes are coregulated and, thus, likely to participate in the same process.

Recombinant DNA technology was born in the 1960s and 1970s when investigations with bacteria revealed the presence of restriction enzymes, proteins that cleave DNA at specific sites, giving rise to DNA restriction fragments.

Principle of Immunoassay: An assay is a general term for an analytical laboratory procedure designed to detect the presence of and/or the quantity of a drug in a biological fluid such as urine or serum (the fluid component of the blood obtained after removal of blood cells and fibrin clot). Microbes are simple, easily manipulated systems. The traditional approach to genetics has been to identify genes on the basis of their contribution to phenotype, or the collective structural and physiologic properties of an organism.

The genetic study of microbes has played a highly significant role in the recent developments in molecular biology, recombinant DNA technology and the preparation of useful products such as insulin, human growth hormone and blood clotting factors. For example, the Hardy-Weinberg formula , p 2 + 2 p q + q 2 = 1, predicts the frequency of individuals with the respective homozygous dominant ( A A ), heterozygous ( A a ), and homozygous recessive ( a a ) genotypes in a randomly mating population. In a series of experiments, mice were injected with live or killed encapsulated or nonencapsulated Streptococcus pneumoniae, as indicated in experiments A through D. The key experiment is D, showing that the killed encapsulated bacteria could supply a factor that allowed the nonencapsulated bacteria to kill mice. Why microbial genetics?
