Ososayensi baseChina benza izibungu ezikwazi ukukhiqiza usilika wesicabucabu onamandla amakhulu

Seda

Sikhona ngempelasonto futhi, ngaphambi kokuqala okusha, ngithanda ukuthi sime isikhashana futhi siqonde ukuthi umhlaba wezofuzo uphendukela kuphi. Kulokhu ikakhulukazi, ngifuna ukukutshela ngephrojekthi yaseChina lapho, ngenxa ye- ukuguqulwa kwesibunguYebo, bangaqala ukwenza usilika wesicabucabu.

Ukuqonda okuncane okushiwo yile phrojekthi nokuthi kungani kutshalwa imali eningi yezinsizakusebenza zabantu nezomnotho ekukhuleni kwayo, ngikutshele ukuthi namuhla izakhiwo zesihlalo sesicabucabu zenza le nto ibe yinto engakholeki, ikakhulukazi impahla yayo eyenza ukumelana nokudonswa nokudonsa.

Ngenxa yale phrojekthi, isibungu sikasilika singenza usilika wesicabucabu

Ukuthola umbono olula wokuthi kungani laba bacwaningi baseChina bebenentshisekelo kulolu hlobo lwezinto ezibonakalayo, ngikutshele ukuthi ezingeni elifanele, uma sithenga isilikhi sesicabucabu ngenye into, isibonelo, singathola ukuthi lokhu kunamandla kunensimbi, ngesikhathi esifanayo nokuthi kungaba nezimo futhi ukukhanya okusho ukuthi kungenzeka isetshenziselwe inombolo enkulu yezinhlelo zokusebenza.

Inkinga esinayo namuhla lapho sisebenzisa isilikhi sesicabucabu akuyona enye ngaphandle kokuthi kunzima kakhulu ukuvuna ngasikhathi sinye ukuthi kudinga indlela enzima kakhulu. Ngenxa yalokhu nokukhulisa ukukhiqizwa kwayo ngangokunokwenzeka, kwenziwe izivivinyo ngezilwane ezahlukahlukene lapho sithola kubhejwa okunengqondo njengezimpethu zasendlunkulu noma kunjaloakuvamile'ungafika kanjani ekuguqukeni kwezimbuzi.

Izimbuzi zishintshwe izakhi zofuzo ukuze zenze usilika wesicabucabu

Ngaphambi kokuqhubeka, ngoba impela indaba yezimbuzi izobe ikushiyile, njengami ngaleso sikhathi, udidekile, ukukutshela ukuthi bekuyisixazululo nje kuphela futhi ngokuyisisekelo lo mqondo ubuqukethe ukuguqulwa kofuzo ukuze izilwane zibe abakwaziyo ukukhiqiza amaprotheni abamba izicabucabu obisini lwabo. Ngokumangazayo, le bekuyindlela engaqondile yokukubiza ngokuthi ekugcineni abacwaningi bakhethe ukusebenzisa isilwane esikhiqize ikomkhulu labo ngokwaziwa kakhulu njengempethu kasilika.

Njengoba sonke sazi, okunye okuyisici esikhethekile sesibungu sikasilika ukuthi ukusuka kusibungu kuya kwinundu, lokhu kusongwe ngochungechunge lwemicu abazikhiqizayo bona uqobo. Le yimicu eguquliwe ngenxa yochungechunge lwezinguquko zofuzo ezinsizeni. Ngempela okwenziwe ngabaphenyi kwaba engeza i-DNA kusuka kuzicabucabu ze-weaver ze-DNA kuya ku-DNA yesikelemu. Imiphumela yayishesha futhi okuqukethwe kukasilika wesicabucabu emicuweni eyenziwe isilwane kwakungokuka- 35.2%.

izakhi zofuzo

Kusasele ibanga elide okusamele lihanjiswe ngaphambi kokuba kuthengiswe ngosilika besicabucabu

Manje lezi zintuthuko akusho ukuthi ekugcineni sisele negxathu elilodwa ekwakheni usilika wesicabucabu othakazelisayo ngoba amanani adingekayo kulokhu kusekude futhi nezidingo, ngokwezindleko zomnotho, ukufeza ukukhiqizwa okuzinzile zisephezulu kakhulu. Ngenxa yalokhu, leli qembu labaphenyi liphinde lihlole ezinye izindlela njengokungeza i-DNA kusuka kuzicabucabu ze-weaver ze-alfalfa ngisho nase-E. Coli, ngeshwa akekho noyedwa kubo okwazile ukukhombisa ukuthi uyisixazululo sokwengeza ukukhiqizwa ulwembu lwesicabucabu.

Njengoba kumenyezelwe, ngokusobala umqondo waleli qembu labaphenyi ngukwenza ngcono inqubo lapho umbungu kasilika ukhiqiza khona lolu chungechunge lwemicu lukhetheke kakhulu ngoba, phakathi kwezinye izinzuzo, le ndlela yenza usilika ilungele ukusetshenziswa ngokushesha lapho iphothwa yilesi sinambuzane, okungukuthi, akudingeki ukuthi ikhishwe noma icutshungulwe nganoma iyiphi indlela. Ngakolunye uhlangothi, ukucwengisiswa okuqhubekayo nokuhlolwa ngale ndlela kungayivumela ukuthi ivumelane nezimo ezintsha ezingakatholakali.
