Step-by-step explanation:
Bacteria are microorganisms with an extraordinary ability to adapt to different
environmental conditions. To understand the essence of this ability it is important to know
their genetic bases, that is how genetic information is organized, how they perform and
regulate their expression and what mechanisms of gene variation they possess.
The infectious capacity of pathogenic bacteria is that they possess the information
gene necessary to colonize host tissues, invade and / or produce substances
Toxic that will cause the disease.
On the other hand, knowledge of the genetic functioning of bacteria, added to the
The fact that they are easy to use in the laboratory and that they have rapid growth has allowed them to be used to synthesize useful products for medicine, both for diagnosis and
for the prevention and treatment of some diseases. These possibilities have been seen
increased with the development of genetic engineering and the availability of technical
molecular biology.
