### Step-by-Step Solution for the Question on Genetic Engineering and rDNA Technology

**What is Genetic Engineering?**
Genetic engineering is the manipulation of genetic material, which involves adding, deleting, or altering DNA sequences in an organism's genome. This process allows scientists to introduce specific traits into a host organism, thereby changing its phenotype. For example, the introduction of the BT gene into cotton plants makes them resistant to pests.
