Ubwubatsi bwa genetike nifatizo ya bioengineering igezweho. Ubwubatsi bwa genetike (cyangwa injeniyeri yubuhanga, tekinoroji ya gene recombination) nugukata no guhuza genes yibinyabuzima bitandukanye muri vitro, ukabihuza na ADN ya vectors (plasmide, fage, virusi), hanyuma ukayimurira muri mikorobe cyangwa selile kugirango ikoronize, kugirango genes yimuwe ishobora kugaragarira muri selile cyangwa mikorobe kugirango ikore proteine ​​zisabwa. Ibice birenga 60% byagezweho n’ibinyabuzima byibanze mu nganda zimiti kugirango biteze imbere imiti mishya iranga cyangwa bitezimbere ubuvuzi gakondo, ibyo bikaba byaratumye habaho impinduka zikomeye mu nganda zimiti n’iterambere ryihuse ry’ibinyabuzima. Biopharmaceutical ninzira yo gukoresha tekinoroji ya bioengineering mubijyanye no gukora ibiyobyabwenge, icy'ingenzi muri byo ni ingengabihe ya geneti. Nukugabanya, gushyiramo, guhuza no guhuza ADN ukoresheje tekinoroji ya cloni hamwe nubuhanga bwumuco wa tissue, kugirango ubone ibikomoka ku binyabuzima. Imiti y’ibinyabuzima ni imyiteguro ikoreshwa mubinyabuzima yateguwe hamwe na mikorobe, parasite, uburozi bwinyamaswa hamwe nuduce tw’ibinyabuzima nkibikoresho byo gutangira, ukoresheje inzira y’ibinyabuzima cyangwa tekinoroji yo gutandukanya no kweza, no gukoresha ikoranabuhanga ry’ibinyabuzima n’isesengura kugira ngo ugenzure ubuziranenge bw’ibicuruzwa biciriritse n’ibicuruzwa byarangiye, harimo inkingo, uburozi, uburozi, serumu, ibikomoka ku maraso, imyiteguro y’ubudahangarwa, cytokine, antigens antibodiyite za Monoclonal hamwe n’ibikoresho by’ubuhanga bwa geneti (ADN recombination Products, in vitro diagnostic reagents), nibindi. mu byiciro bitatu ukurikije imikoreshereze yabo itandukanye: imiti yubuhanga bwubuvanganzo, inkingo z’ibinyabuzima na reagent yo kwisuzumisha. Ibicuruzwa bigira uruhare runini mugupima, gukumira, kugenzura ndetse no kurandura burundu indwara zanduza no kurengera ubuzima bwabantu.
