More advancement in genetic engineering is due to

Options

A. Restriction endonuclease
B. Reverse transcriptase
C. Protease
D. Zymase

Answer

**Step-by-Step Solution:**

1. **Understanding Genetic Engineering**: Genetic engineering involves manipulating DNA to create new genetic sequences. This includes processes like cutting, pasting, and ligating DNA fragments to form modified DNA that can express desired traits.

2. **Identifying the Key Components**: In genetic engineering, specific DNA sequences are targeted. Some portions of DNA may be non-functional or less useful, while others may contain valuable genetic information.

3. **The Role of Restriction Endonucleases**: The advancement in genetic engineering is significantly attributed to the development of restriction endonucleases. These enzymes are capable of cutting DNA at specific locations, allowing scientists to remove unwanted segments and insert useful ones from other DNA sources.

4. **Importance of Cutting and Ligation**: Without restriction endonucleases, the processes of cutting DNA and ligating new sequences would not be possible. This would hinder the ability to create genetically modified organisms or to conduct various genetic engineering techniques.

5. **Conclusion**: Therefore, the primary reason for advancements in genetic engineering is the development and application of restriction endonucleases, which facilitate the precise manipulation of DNA.

**Final Answer**: More advancement in genetic engineering is due to the development of restriction endonucleases.
