To write a successful research paper on genetic engineering, the writer must first know what the subject is all about. Genetic engineering is the manual addition of new DNA to an organism to add one or more new traits that are generally not found in that organism. It is also called genetic modification. Aside from introducing additional copies of a gene to an organism, it may also mean changing or replacing one base pair or even deleting a whole region of DNA. It could also mean taking DNA from one organism and mixing it with the DNA of another. All these processes are used by scientists to modify certain characteristics of an individual organism. As an example, genetic engineering is used to create plants that have a higher nutritional value or are able to tolerate exposure to herbicides.

The process of creating a transgene begins by isolating the gene of interest from a donor organism or selecting for purchase any of the thousands of known genes from massive online genomic databases. Once the gene is obtained, it is usually altered so it can function more effectively or be expressed more readily in the host organism. That gene is then combined with other genetic elements and introduced into a second organism (the host), at which point it’s known as a transgene. A transgenic organism is further defined as one that contains a transgene introduced by technological methods rather than through selective breeding. Hybrids are transgenic organisms created when reproductive cells from two species combine to form a single embryo (e.g., a mule is the offspring of a horse and a donkey); on the other hand, chimeras are created by artificially combining genetic material from two organisms into a single species.
