Hint: Transgenic organisms contain foreign DNA that has been introduced using biotechnology. Foreign DNA is a DNA of another species, or else recombinant DNA from the same species that has been manipulated in the laboratory then reintroduced into an organism.
Complete step by step answer: Early diagnosis of the disease cannot be done with the help of transgenic animals. It can only be done through various techniques, such as PCR and ELISA. Transgenesis allows improvement of nutrients in animal products, including the quantity, the quality of the whole food, and the specific nutritional composition. Transgenic technology could provide a means of transferring or the increasing nutritionally beneficial traits in organisms. It can also provide animal models of human disease to help the researchers to find new treatments in the field of medicine.
i. Transgenic animals are animals that have had a foreign desired gene inserted into their genome. Such animals are most commonly created by a process called microinjection of DNA into the pronuclei of a fertilised egg which is subsequently implanted into an oviduct of the pseudopregnant surrogate mother. Transgenic animals usually, mice or rats are used for this type of research.
ii. Applications of animal transgenesis may be divided into the following categories:
a. One is to obtain information on gene function and regulation as well as on human diseases, secondly to obtain high-value products to be used for human therapy.
Hence, the correct answer is option B.
Note: After the successful production of transgenic mice, the scientists easily made rabbits, sheep, pigs, etc. These animals are of great importance to humans, as they provide benefits economically as well as medically to identify certain diseases. They are also important in agriculture.
