13.7.1 Genetic Engineering
**Genetic Engineering:** Genetic engineering is a process that uses **laboratory-based technologies** to modify the DNA structure
Explanation level
Introduction
Genetic engineering is a process that uses laboratory-based technologies to modify the DNA structure of an organism. Genetic engineering aims to alter the genes to enhance the capabilities of the organism.
The principle of genetic engineering is to manipulate and modify the genetic material of an organism by adding, removing, or repairing part of the genetic material (DNA) and to incorporate desirable traits.
This section explains what genetic engineering is, its principle, and its aims.
Definition
Genetic Engineering: Genetic engineering is a process that uses laboratory-based technologies to modify the DNA structure of an organism.
In simple words: Genetic engineering is the process of changing the DNA of an organism using laboratory techniques to give it new or improved traits.

Common Mistakes
| Mistake | Correction |
|---|---|
| Thinking genetic engineering is the same as gene therapy | Genetic engineering is the process of modifying DNA; gene therapy is a medical technique that uses genetic engineering to treat disease |
| Forgetting the principle of genetic engineering | The principle is to manipulate and modify genetic material by adding, removing, or repairing part of the DNA |
| Thinking genetic engineering only involves adding DNA | Genetic engineering can involve adding, removing, or repairing DNA |
| Forgetting the aims of genetic engineering | Aims include producing vaccines, life-saving drugs, pharmaceutical development, and treatment of disease |
| Thinking genetic engineering is only used in medicine | Genetic engineering is also used in agriculture, biotechnology, and research |
| Confusing genetic engineering with cloning | Genetic engineering involves modifying DNA; cloning involves creating genetically identical copies |
| Thinking genetic engineering is always safe | Genetic engineering has ethical, social, and environmental implications that need to be considered |
