Inserting pieces of DNA, which will result in pest or disease resistance in a crop.C. Injecting growth hormones into seeds or pregnant animals.D. Cloning of good producersto make millions of offspring.

Answer 1

Genetically modified organisms are created by

B. Inserting pieces of DNA, which will result in pest or disease resistance in a crop.

Step-by-step explanation:

A genetically modified organism (GMO) is an organism in which the genetic material has been changed using techniques of genetic engineering . Genes have been transferred within the same species, across species (creating transgenic organisms) and even across kingdoms. New genes can be introduced, or endogenous genes can be enhanced, altered or knocked out.

Creating a genetically modified organism is a long process. The gene that genetic engineers wish to insert into the host organism must be isolated and fused it with other genetic elements. A number of techniques are available for inserting the isolated gene into the host genome. Recent advancements using genome editing techniques like CRISPR-Cas9 that can be used to edit genes within organisms have made the production of GMO's much easier.
