----------------------------------------------------------------------------------- History of The Domestication of Dogs: Are Dogs our Companions or Are We Their Companions? (ii) chemical safety testing? These animals are all considered useful as ailment models & producers of the substances for the welfare of humans. For example, transgenic mice, rats, rabbits, pigs, sheeps, cows and fish have been produced. Transgenic animals are the animals with genome that was changed in order to bring genes coming from other species. Biopiracy refers to the use of bio-resources by multinational companies and other 2. 4. Cattle can produce milk that contains particular proteins which could help in the treatment of emphysema. These animals are also used for the toxicity or safety testing procedures. (image 1.1 and 1.2) Mutagenesis and function disorders. (ii) Traditional knowledge related to bio-resources can be exploited to develop modern applications and to save time, efforts and expenditure. Transgenic animals are known to be used in testing various medicines and other medical treatments that different universities and other pharmaceuticals are experimenting. [Delhi 2009] [All India 2011; Foreign 2010] Grows easily than of real animals. Those humans observed and chose organisms from natural selection to select and breed organisms that showed characteristics desired by them and this began the process of selective breeding. 2. 10. The transgenic cow, Rosie, produced human protein-enriched milk (2.4 gm/L). 2. This milk contained the human a-lactalbumin and was more ‘nutritionally balanced for human babies than natural cow milk. Ans. 8.7% of animals are used to benefit society by testing out cures for diseases and safety evaluation. consistently produces offspring of the same recognizable traits or to enhance the quality of an (2.4 g/L). With the use of transgenic animals, people are able to make use of gene therapy and insulin produced by these animals to cure or help in treating particular diseases. It contained the human a-l actalbumin and was nutritionally more balanced product for human babies than natural cow’s milk. Benefit # 5. This is permitted since it is said that animals’ bodies are almost the same as humans, and the reaction of animals towards medicines and injections will tell scientists of possible reactions with humans. The topic of transgenic animals is really just on ethical beliefs. Transgenic Mouse Model . (f) Besides Basmati rice, now attempts are in progress for turmeric and neem (Indian traditional herbal medicines). Several gene and insulin needs of humans are provided by such animals. With just a single experimentation, the possible numbers of animals that can be killed are countless. such of a technology, is known as the recombinant DNA technology, it, milleniums, with “treatises as much as 2000 years old” giving advice on selective breeding, humans have carried out genetic manipulation on other organisms for their own benefit. Check with reference to genetic In the side of experts, there are particular pros that are found to be helpful and some of these are the following: 1. The advantages and disadvantages of these modifications to the grains will be discussed, ethical issues of these modifications will also be looked at and a decision on how all of these factors may affect the country will be looked at. 7. But with various ways developed in testing particular discoveries, experts should consider using new ways of testing instead of risking the lives of animals. compounds, or to adapt to different environments. Since 1960, there are many introducing genetic engineering in crops production as it can bring a lot of benefits e.g. [All India 2008] Explain any four ways in which such animals can be beneficial for humans. Different animals are used to test any new medicines and treatments that scientists would discover for treating human diseases. polio vaccine. Essay on African Americans During the Post World War II Era, Environmental Impact Assessment: Identifying the Environmental Effects of a Project, History of the Ultrasonic Technology Essay, Effective Curriculum Models for Gifted and Talented Students. 1 Mark Questions May kill many animals especially when experiments fail. Since there are pros of using transgenic animals, it is necessary that you would also know the cons of using these animals. These animals are of great importance in human life as they provide benefits economically as well as medically to identify certain diseases. Biopiracy should be prevented. The benefits of using transgenic animals include the possibility of the replacement of higher species by lower species- through development of disease models in mice rather than in dogs or non-human primates, the extent of discomfort experienced by parent animals during the experimental procedures. The site below explains these disadvantages listed below and others. Animals that have had their DNA manipulated to possess and express an extra (foreign) gene are called transgenic animals. Animals may be too big for their legs, have shorter life spans, and there are low survival rates for transgenic aimals. (iii) Some nations are developing laws to prevent such unauthorised exploitation of their bio-resources and traditional knowledge. 2.0 Genetic modified crops worldwide----------------------------------------------------------------------------- (a) Human protein (a-1 antitrypsin) is used to treat emphysema.
