In this article we will discuss about the meaning of transgenic mice. Cloned genes can be introduced into the germ line cells of an animal allowing study of the intact animal rather than in cultured cells. For this purpose, the nucleus in mouse embryonal cells has been used for injecting foreign DNA. The goal in such experiments is to have [...]
In this article we will discuss about the definition and strategies of genetic engineering. Definition of Genetic Engineering: The deliberate modification in genetic material of an organism by changing the nucleic acid directly is called genetic engineering. Genetic engineering holds the potential to extend the range and power of every aspect of biotechnology. The techniques will be used widely to [...]
In this article we will discuss about the purpose and basic steps of genetic engineering. Purpose of Genetic Engineering: The interest in genetic engineering principally is due to its varied applications (Fig. 22.1): 1. Production of varieties of plants having particular desirable characteristics (e.g., resistance or tolerance to disease, drought, 'development of CMS line, etc.). 2. Improvement in the production [...]
