Why are transgenic mice being developed?

Options

  1. ATo study the regulation of genes
  2. BTo test the safety of vaccines
  3. CTo increase the size of mice
  4. DTo enhance their physical abilities

Correct answer

B. To test the safety of vaccines

Step-by-step solution

Biological products: Medicines required to treat certain human diseases can contain biological products, but such products are often expensive to make. Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (or genes) which codes for a particular product such as human protein (α-1-antitrypsin) used to treat emphysema. Similar attempts are being made for treatment of phenylketonuria (PKU) and cystic fibrosis. In 1997, the first transgenic cow, Rosie, produ
