Scientists have recently modified the bacteria that cause tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. What is this process called?
A) genetic engineering
B) biological vector
C) mechanical vector
D) electrophoresis

It includes isolation, cloning and transfer of of desired genes in to the host genome (within or across the species) in order to produce organism with desired characteristics (such as pest resistance, high yield et cetera).

The organism produced through genetic engineering is termed as genetically modified organism (GMO).

Examples may include in-situ production of insulin, Bt-cotton et cetera.
