Answer:
modifying an organism’s natural characteristics through changes to its genetic material.
Step-by-step explanation:
Genetic engineering is the manipulation of the genetic material of an organism using biotechnology. This is usually done with the goal of creating improved or new organisms. The process can either take the form of "adding" genes that give particular characteristics to the organism, or "removing" genes in order to get rid of particular characteristics. An organism that has gone through this process is usually considered to be genetically modified (GMO).
