Transgenic animals can be classified as traditional transgenics where a gene is inserted at a random location in the genome or gene-targeted transgenics (knock-outs, knock-ins, and conditional knock-outs) where
Provides technical services such as genetic breeding, speed expasion, embryo cryopreservation, strain rederivation and strain rescue. Strictly monitors the environment inside the barrier, regularly tests the laboratory animals and their environmental microorganisms to strictly control the quality of the anima...
Transgenic plants and animals result from genetic engineering experiments in which genetic material is moved from one organism to another, so that the latter will exhibit a characteristic. Business corporations, scientists, and farmers hope that transgenic techniques will allow more cost effective and pr...
the ability to generate transgenic farm animals relied on methods of passive transgenesis. In recent years, significant improvements have been made to introduce and apply active techniques of transgenesis and genetic engineering in these species. These new approaches dramatically enhance the ease and spee...
Genetic engineering of crops and animals through the use of DNA is prodicing a great change in food production.It is also starting a battle between those who believe in its promise and critics who doubt" and fear it. The potential to improve the quality" and nutritional value of the vegetab...

阅读理解Genetic engineering, in its broadest definition, means to control a species so that a particular trait is increased in the population. A trait is how an organism(有机体) looks or acts or what it does. Having brown eyes is a trait. Flying in circles is a trait. Climbing trees is...
genetic engineering that introduces specific genes. (Ref. 1) Since the process is rather straightforward, it is relatively faster than selective breeding (seeprevious tutorial) in terms of coming up with crops with the desired traits. Examples of genetically-engineered plants with more desirable ...
