If he researcher to change the order normative molecule (DNA) in the cell is expected to reflect this change in particular on the special nature of this cell, and such changes in the qualities of hereditary often occur in nature, this phenomenon is known mutation (Mutation) any change in the nature of genes to the cells of the organism, whether as a result of mating or insemination, or to physical processes Kaltaarb to radiation or chemicals.And has paved the results obtained by scientists Apple and Trotner to the development of a new science is genetic engineering, where they knew that there were types of bacteria have the ability to accept the genetic material of Foreign Affairs through the phenomenon of a process known as transfer or transformation (Transformation) Vlahza that one of the types of bacteria ( Bacillus Subtilis) can carry (DNA) and enable the smallpox virus from reproducing within the bacterial cytoplasm.In 1973, enter the de researcher and his colleagues is a new scientific term gene transfer ((Transgenesis and is intended to transfer genetic information from the primitive cells into the cells of luxury.Are sometimes the process of vaccinating cells prokaryotic substance of the (DNA) of Foreign Affairs of the failure is attributable in many cases, to digest this the (DNA) is strange or not being able to follow the effects of the new order to be carried Article Genetic new and reproduction must provide two basic conditions:1 - These contain the hereditary material to what is known as the status of reproduction (Origin of Replication).2 - The combination of these genetic material with the genetic material of the host organism.Perhaps the most important reasons that led to the development of Genetic Engineering is the knowledge that the molecule (DNA) sometimes has the ability to multiply in host cells.
