Report Abuse. A genetically modified organism (GMO) is an organism whose genetic [material] has been altered using techniques in genetics generally known as recombinant DNA technology. Recombinant DNA technology is the ability to combine DNA molecules from different sources into the one molecule in a test tube.Thus, the abilities or the phenotype of the organism, or the proteins it produces, can be modified through the modification of its genes.eport Abuse.
