When scientists take the genes of two different species and combine them, we call this genetic engineering or recombinant DNA technology.

Here's why:

* Genetic engineering refers to the direct manipulation of an organism's genes using biotechnology.

* Recombinant DNA technology specifically involves combining DNA from different sources to create a new DNA sequence.

This process has many applications, including:

* Creating genetically modified organisms (GMOs) with desired traits, such as pest resistance or increased yield in crops.

* Producing pharmaceuticals, like insulin, using bacteria or yeast.

* Developing gene therapies to treat genetic disorders.

While it's a powerful tool, there are also ethical considerations and potential risks associated with genetic engineering.
