If the researcher can change the base order of the DNA in the cell, it is expected that this change will be reflected in a certain way on the special nature of this cell. Such changes in genetic characteristics often occur in nature. This phenomenon is known as mutation, The genes of the organism's cells, whether as a result of mating or pollination, or of physical processes such as exposure to radiation or chemicals.
The results obtained by Apple and Trotner have led to the development of a new science of genetic engineering. They know that there are a number of bacteria that have the ability to accept external genetic material through a process known as transformation. They noticed that one type of bacteria (Bacillus Subtilis can carry a root virus and enable it to reproduce within the bacterial cytoplasm.
In 1973, he and his colleagues introduced a new scientific term, transgenesis, which is meant to transfer genetic information from primitive cells to their higher cells.
Sometimes the process of vaccinating the cells of the rudimentary nucleus with the external material (DNA) of failure is often due to the digestion of this strange DNA or can not trace its new effects In order to carry the new genetic material and its reproduction, there must be two basic conditions:
1 - contain this genetic material on the so-called breeding center (Origin of Replication).
2. Combine this genetic material with the genetic material of the host organism.
One of the most important reasons for the evolution of genetic engineering is the knowledge that DNA sometimes has the ability to multiply in host cells.
