Question

Why are these animals being produced? Explain any four reasons.

Hint:

In PCR, each cycle doubles the amount of DNA, leading to exponential amplification. The key to success in PCR is using a heat-stable polymerase enzyme like Taq polymerase.

Answer 1

Transgenic animals are produced for various purposes, including:
1. Production of therapeutic proteins: Some transgenic animals are engineered to produce proteins like insulin, growth hormones, or antibodies in their milk, blood, or other bodily fluids.
2. Disease research: Transgenic animals are used to study human diseases by introducing specific genes associated with these diseases into the animals, allowing researchers to understand the progression and treatment.
3. Improved agricultural traits: Transgenic animals may be created to have better growth rates, disease resistance, or enhanced production of meat, milk, or eggs.
4. Pharmaceutical production: Transgenic animals are used in the production of biopharmaceuticals, such as in the case of "pharming," where animals are genetically modified to produce medically useful proteins.
