These issues need to be considered by all stakeholders, including veterinarians, to ensure that all parties are aware of the ethical issues at stake and can make a valid contribution to the current debate regarding the creation and use of genetically engineered animals. In addition, it is ...
Genetically Modified Food: Ethical Issues 来自 ResearchGate 喜欢 0 阅读量: 58 作者: PB Thompson 摘要: The use of recombinant DNA technology to transform agricultural plants and animals has been the subject of ethical controversy for the last quarter century. The argument favouring these technologies ...

allows the serial production of genetically engineered animals that can be used as animal “donors” for xenotransplantation; allows to expand the n.º of chosen livestock, so that we can have more and better food. * Ex.: Polly, a transgenic sheep that has a human gene in every cell of...
Similar to the other farm animals, chicken have a strong pecking order by which the birds can recognize each other in flock up to approximately 50-60 other birds on the basis of their head form. Larger groups makes them socially unstable group and create a risk of serious pecking problems,...

studying specific areas of molecular biology by rotating through several different "stations." There, they learn how to manipulate DNA, synthesize bacterial proteins, microscopy, bioinformatic analysis of genomic sequences, and how to work with animals, in their case, the African frog Xenopus laevis...
After human or animals eat transgenic plants (such as potatos or tomatoes) expressing the oral vaccine, the released antigens are identified and swallowed by ruffled cells (M cells) in intestinal mucosa associated with lymphoid tissue (such as Peyer's patch), and then are transferred to lower...
