Mark the correct statement with respect to application of biotechnology :"

Options

A. Rosie was the first transgenic cow that possesses gene for production of human ` alpha `- lactalbumin
B. Transgenic mice are not used for testing the safety of polio vaccine
C. GEAC is an organisation that reserves the right to issue global patent rights
D. Gene for production of hirudin has been introduced in sheep

Answer

To answer the question regarding the correct statement with respect to the application of biotechnology, we will analyze each option provided:

1. **Option 1:** "Rosie was the first transgenic cow that possesses gene for production of human alpha-lactalbumin."
- This statement is **correct**. Rosie was indeed the first transgenic cow, and she was genetically modified to produce human alpha-lactalbumin, a protein that is beneficial for human infants.

2. **Option 2:** "Transgenic mice are not used for testing the safety of polio vaccine."
- This statement is **incorrect**. Transgenic mice are widely used in research, including testing the safety of vaccines such as the polio vaccine, due to their genetic similarities to humans.

3. **Option 3:** "GEAC is an organization that reserves the right to issue global patent rights."
- This statement is **incorrect**. The Genetic Engineering Appraisal Committee (GEAC) is responsible for regulating the use of genetically modified organisms in India, but it does not deal with global patent rights.

4. **Option 4:** "Gene for production of hirudin has been introduced in sheep."
- This statement is **incorrect**. The gene for hirudin, an anticoagulant, has been introduced into a plant species known as Brassica napus, not in sheep.

After analyzing all the options, the correct statement is:

**Correct Answer:** Rosie was the first transgenic cow that possesses gene for production of human alpha-lactalbumin.
