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. Learn about the his
Genetic Engineering The human manipulation of the genetic material of a cell. Genetic engineering involves isolating individual DNA fragments, coupling them with other genetic material, and causing the genes to replicate themselves. Introducing this created complex to a host cell causes it to multiply ...
The earliest forms of genetic engineering occurred on farms. People selected seeds from plants that had more fruit production or tastier leaves than other plants of their types. Then they chose to save the seeds from the best of that lot to sow the next year. So, year by year, the farmer...
