Question

what is a genetically modified organism (gmo)?
an organism that is only made for human use.
an organism whose genetic material has been altered using genetic engineering techniques.
an organism that has no meaning and use besides just fun.

Explanation:

A genetically modified organism (GMO) is defined by the alteration of its genetic material through genetic engineering techniques. The first option is incorrect as GMOs are not solely "made for human use" in that simplistic sense. The third option is also incorrect as GMOs have various purposes like improving crop yields, etc., and are not just for "fun".

Answer:

An organism whose genetic material has been altered using genetic engineering techniques.
