Which of the following statements is true of all genetically engineered organisms?

a. they have a genome that is identical to their parents' genome.
b. they are made using half the genomes of two different species.
c. they contain genes transferred from another organism.
d. they are produced by breeding only the individuals with desired traits.

The right answer is C

Molecular biology and genetic engineering are at the basis of biotechnologies, in particular those based on recombinant DNA and genetic transformations.

It consists of introducing a gene into a DNA ring (plasmid). This plasmid is then transferred to bacteria. For example, if a human gene is introduced into a bacterium, it will produce the corresponding human protein, which is then isolated from bacteria, purified and ultimately used as a substitute drug.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
