Which of the following is part of Genetic engineering :

Options

A. Use of restriction endonuclease on bacterial DNA and formation of new traits
B. Use of Ligase for cutting DNA
C. Developing instruments
D. Use of statistic in genetics

Answer

To determine which of the options is a part of genetic engineering, we need to analyze each option in the context of recombinant DNA technology. Here’s a step-by-step solution:

### Step 1: Understand Genetic Engineering
Genetic engineering, also known as recombinant DNA technology, involves manipulating an organism's DNA to achieve desired traits. This process often includes cutting DNA, joining DNA fragments, and introducing new genes into a host organism.

### Step 2: Analyze the Options
1. **Use of restriction endonucleases on bacterial DNA and formation of new traits.**
- **Explanation:** Restriction endonucleases (or molecular scissors) are enzymes that cut DNA at specific sequences. This is a fundamental step in genetic engineering, as it allows for the isolation of specific genes from a DNA molecule, which can then be inserted into a vector (like plasmid DNA) to create recombinant DNA.
- **Conclusion:** This option is a correct part of genetic engineering.

2. **Use of ligase for cutting the DNA.**
- **Explanation:** Ligase is an enzyme that joins DNA fragments together, not cuts them. It is used after the DNA has been cut by restriction enzymes to ligate the foreign DNA into the vector.
- **Conclusion:** This option is incorrect since ligase does not cut DNA.

3. **Development of instruments for genetic analysis.**
- **Explanation:** While instruments are important in genetic analysis, the development of these instruments is not a direct part of genetic engineering itself.
- **Conclusion:** This option is incorrect.

4. **Use of statistics in genetics.**
- **Explanation:** Statistics can be used in genetics for data analysis and interpretation, but it is not a part of the actual process of genetic engineering.
- **Conclusion:** This option is incorrect.

### Step 3: Final Conclusion
Based on the analysis of the options, the only correct answer that is part of genetic engineering is:

**Correct Answer: Use of restriction endonucleases on bacterial DNA and formation of new traits.**
