Recombinant is a term used in the field of genetics to describe a molecule or organism created by the combination of DNA from different sources. There are several synonyms for the word recombinant that are commonly used, including chimeric, hybrid, and engineered. Chimeric refers to a molecule or organism made up of genetic material from two or more different species. Hybrid refers to a combination of genetic material from two different individuals of the same species. Engineered refers to genetic material that has been deliberately modified or manipulated to produce a desired trait. All of these terms are used to describe the same basic concept of mixing and matching genetic material to create something new and unique.
