Genetic Engineering, Modification And Its Real-World Applications

Genetic Modification: An Overview

Genetic modification primarily involves manipulating the DNA of an organism to achieve desired characteristics. The process may include inserting, deleting, or modifying specific genes, leading to the expression of desired traits. This technology has evolved significantly, allowing scientists to work with precision at the molecular level.

Techniques of Genetic Modification:

• CRISPR-Cas9: This revolutionary technique enables precise editing of genes. It acts like molecular scissors, allowing scientists to cut and replace specific DNA sequences.

• Gene Therapy: In the medical field, gene therapy involves introducing, deleting, or replacing genes to treat or prevent diseases.

• Recombinant DNA Technology: This classic technique involves combining DNA from different sources, creating novel genetic combinations.
