Genetic engineering, the artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules to modify an organism. The term is generally used to refer specifically to methods of recombinant DNA technology.
Genetic engineering is a process that alters the genetic structure of an organism by either removing or introducing DNA or modifying existing genetic material in situ.
Modern genetic technologies like genome editing would not be possible without all the previous generations of genetic technologies that have enabled scientists to discover what genes are, what they do and how DNA can be modified to add, remove or replace genes.
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism.
