Transgenic animals are animals that have had foreign genetic material inserted into their genome. This can be done for a variety of reasons, such as to produce a protein that is not normally produced by the animal, to change the animal's appearance, or to treat a genetic disorder.
Transgenic animals are often used in research to study how genes work and to develop new treatments for diseases. For example, transgenic mice have been used to study the effects of genetic disorders on brain development. This knowledge has led to the development of new treatments for these disorders, such as drugs that can correct the genetic defect.
The process of transgenic animal creation typically involves the following steps:
Selecting a cell line that is capable of producing a protein of interest.
Isolating a DNA fragment containing the foreign genetic material.
Inserting the DNA fragment into the cell line.
Selecting for cells that have successfully integrated the DNA fragment.
Growing the cells and selecting for those that produce the desired protein.
Transmitting the DNA fragment into other cells or tissues.
Transgenic animals offer a wide range of possibilities for research and biotechnology applications. They provide scientists with the ability to study the effects of genetic variation on various traits and develop new therapies for diseases
