Genetic engineering ndiye maziko a bioengineering yamakono. Ma genetic engineering (kapena genetic engineering, gene recombination technology) ndikudula ndikuphatikiza majini amitundu yosiyanasiyana mu m'galasi, kuwalumikiza ndi DNA ya ma vectors (plasmids, phages, virus), ndiyeno kuwasamutsira ku tizilombo tating'onoting'ono kapena ma cell kuti apange cloning, kotero kuti majini omwe amasamutsidwa amatha kuwonetsedwa m'maselo kapena tizilombo toyambitsa matenda kuti tipange mapuloteni ofunikira. Zoposa 60% za zomwe zapindula mu sayansi ya zamankhwala zimakhazikika m'makampani opanga mankhwala kuti apange mankhwala atsopano odziwika bwino kapena kusintha mankhwala azikhalidwe, zomwe zadzetsa kusintha kwakukulu m'makampani opanga mankhwala ndikukula mwachangu kwa biopharmaceuticals. Biopharmaceutical ndi njira yogwiritsira ntchito ukadaulo wa bioengineering pantchito yopanga mankhwala, chofunikira kwambiri chomwe ndi uinjiniya wa majini. Ndiko kudula, kuyika, kulumikiza ndikuphatikizanso DNA pogwiritsa ntchito ukadaulo wa cloning ndi ukadaulo wa chikhalidwe cha minofu, kuti mupeze zinthu zamankhwala. Tizilombo mankhwala ndi biologically adamulowetsa kukonzekera ndi tizilombo toyambitsa matenda, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda monga zipangizo poyambira, ntchito njira kwachilengedwenso kapena kupatukana ndi kuyeretsa matekinoloje, ndi kugwiritsa ntchito kwachilengedwenso ndi kusanthula umisiri kulamulira khalidwe wapakatikati mankhwala ndi anamaliza mankhwala, kuphatikizapo katemera, poizoni, toxoids, seramu, mankhwala a magazi, kukonzekera kwa chitetezo cha mthupi, ma cytokines, ma antigen Monoclonal antibodies ndi mankhwala opangira majini (DNA recombination products, in vitro diagnostic reagents), ndi zina zotero. m'magulu atatu molingana ndi ntchito zawo zosiyanasiyana: mankhwala opangira ma genetic, katemera wachilengedwe ndi zowunikira zamoyo. Zogulitsazi zikugwira ntchito yofunika kwambiri pakuzindikira, kupewa, kuwongolera komanso kuthetseratu matenda opatsirana komanso kuteteza thanzi la anthu.
