Specifically, the process of taking genes from one organism and inserting them into the cells of another is often referred to as transgenesis.

Here's a breakdown:

* Genetic engineering is a broader term encompassing the manipulation of an organism's genes for various purposes, including transgenesis.

* Gene transfer is a more general term that can refer to moving genes between any cells, not just between different organisms.

* Transgenesis is the specific process of introducing foreign DNA (genes) from one organism into the genome of another organism, resulting in a genetically modified organism (GMO).

Examples of transgenesis include:

* Introducing genes for pest resistance into crops (like corn or cotton)

* Producing human insulin in bacteria for medical use

* Creating bioluminescent animals (like glow-in-the-dark fish)
