Which best describes genetic engineering? fragments of dna that have desired genes are isolated to form recombinant dna for use in a host.
all the dna from a desired organism is isolated to form recombinant dna for use in a host.
different sections of dna from a desired organism are inserted into a host so that beneficial traits will be expressed.
one strand of dna is isolated and inserted into a host so recombinant dna can be formed.

Genetic engineering is best described as : different sections of DNA from a desired organism are inserted into a host so that beneficial traits will be expressed.

Typical example in the past is in the production of human insulin from cows using recombinant DNA technology on a bacteriophage. It is also seen in genetically modified organisms such as with food & plants where improvements can be done to have specific colours, seedless plants, plants that are unusually bigger in size, etc. It is also been explored in areas like immune boosting, transplants, etc eventually to help the human race.
