Since 1981, when the term transgenic was first used by J.W. Applications in Agriculture and the Pharmaceutical Industry. Application of transgenic animals (4) characterize the ability of a promoter to direct tissue-specific gene expression. A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome. The transgenic mice have been genetically modified so that they carry a green fluorescent protein which glows green under blue light. Zoology 2. This science allows us to create specific economic traits through animal products. Genetic engineering is made possible by recombinant DNA technology. Transgenesis is the process by which mixing up of genes takes place. examine the effects of overexpressing and misexpressing endogenous or foreign genes at specific times and locations in the animals, Study gene function, drug testing Transgenic animals A. can be engineered to become factories for manufacturing proteins B. are often obtained from germ line engineering C. will pass the genes on to their offspring D. commonly include mice E. all are correct Organisms that have altered genomes are […] F. Costantini, in Brenner's Encyclopedia of Genetics (Second Edition), 2001. By, DAMARIS BENNY DANIEL II Msc. Ruddle (1981), there has been rapid development in the use of genetically engineered animals as investigators have found an increasing number of applications for the technology. Transgenic Organisms Modern genetic technology can be used to modify the genomes of living organisms. Transgenic animal models of human disease can be useful for preclinical drug testing. 26. Desired gene is identified 2. The DNA in other organism or bacterial DNA is cut open 4. The gene is inserted into the cut DNA 5. The gene is removed from the organisms DNA 3. Foreign genes are inserted into the germ line of the animal, so it can be transmitted to the progeny. The photo shows two transgenic mice positioned either side of a plain mouse. Some transgenic animals are produced for their specific economic traits. Credit: Ingrid Moen et alet al., BMC Cancer,12/21 (2012), 1-10. This procedure, called sperm-mediated gene transfer (SMGT) may someday be able to produce transgenic pigs that can serve as a source of transplanted organs for humans. This process is also known as “genetic engineering.” Genes of one species can be modified, or genes can be transplanted from one species to another. Transgenic pigs have also been produced by fertilizing normal eggs with sperm cells that have incorporated foreign DNA. Gordon and F.H. The inserted gene works in the transgenic (genetically engineered) organism or bacteria. Transgenic Primates Transgenic animals 1. We use antibodies from mice and other rodents to create new medical therapies that can reduce or eliminate the impact of illness and disease. A transgenic animal is one whose genome has been altered by the transfer of a gene or genes from another species or breed. 2. Methods of creation of transgenic animals Animals engineered to be susceptible to human viruses, by introduction of viral receptors or other host range determinants, can also be used for testing human vaccines. 1.

Cattle can produce milk that contains particular proteins which could help in the treatment of emphysema. STEPS OF HOW BACTERIA CAN BE GENETICALLY ENGINEERED TO PRODUCE A HUMAN PROTEIN: 1.
