Which of the following is/are part(s) of biotechnology?
A. in vitro fertilisation
B. synthesis of a gene
C. correcting a defective gene
D. developing a DNA vaccine

Options

A. A,B
B. B,C
C. C,D
D. A,B,C,D

Answer

To determine which of the options are part of biotechnology, we need to analyze each option individually:

1. **In vitro fertilization (IVF)**:
- IVF is a process where an egg is fertilized by sperm outside the body, in a laboratory setting. This technique is widely used in reproductive medicine and is a significant application of biotechnology.
- **Conclusion**: Yes, IVF is part of biotechnology.

2. **Synthesis of a gene**:
- The synthesis of a gene involves creating a specific sequence of DNA that can be used for various applications, such as research, medicine, or agriculture. This process often utilizes techniques like polymerase chain reaction (PCR) and cloning vectors.
- **Conclusion**: Yes, the synthesis of a gene is part of biotechnology.

3. **Correcting a defective gene**:
- Gene therapy is a biotechnological approach that involves correcting defective genes responsible for disease development. This can be achieved through various methods, including CRISPR technology.
- **Conclusion**: Yes, correcting a defective gene is part of biotechnology.

4. **Developing a DNA vaccine**:
- DNA vaccines are a new type of vaccine that uses genetically engineered DNA to induce an immune response. This method is a significant advancement in biotechnology and is used to combat various diseases.
- **Conclusion**: Yes, developing a DNA vaccine is part of biotechnology.

After analyzing all the options, we can conclude that all the options listed (A, B, C, and D) are indeed part of biotechnology.

**Final Answer**: All of the above options (A, B, C, and D) are part of biotechnology.
