Pfupisa nyaya yacho:  Vasayendisiti vokuChina vakabvuma kuti vakachinja majini emwana ari mudumbu romunhu kokutanga. Chiziviso chacho chinosimbisa runyerekupe rwokuti vamwe vanzveri vave vachiita kuedza kwamagene kunopanikirika mutsika. Mamwe masayendisiti akatotyiswa nepfungwa yacho, achityira kuti ingashandiswa zvisina kufanira kubvumira vabereki ku'sarudza' majini avachapfuudza kuvana vavo. Masayendisiti echiChinese akabvuma kuchinja majini emimba yomunhu, akadai seaya ari pamusoro apa, kokutanga munhau. Chiziviso chacho chinotsigira runyerekupe rwokuti vamwe vatsvakurudzi vave vachiita kuedza kusina kururama. Chikwata chacho chakaedza kuchinja majini anokonzera β-thalassemia, chirwere cheropa chinogona kuuraya, vachishandisa nzira yokugadzira utachiona inonzi CRISPR/Cas9. CRISPR inonyatsochinja zvikamu zvinenge zvichida kugadziriswa zveDNA. Kusiyana nemamwe mashandiro anoita kuti majini adzikire, CRISPR inonanga zvinhu zvinobva mugenome uye inodzima majini zvachose padanho reDNA. DNA yakatemwa <unk> inozivikanwa seyakaputsika kaviri <unk> inonyatsotevedzera rudzi rwokuchinja kunoitika nenzira yomuzvarirwo, somuenzaniso pashure pokugara kwenguva refu uri muzuva. Asi kusiyana nemwaranzi yeUV iyo inogona kuita kuti majini achinje, CRISPR inokonzera kuti majini achinje panzvimbo chaiyo. Apo gadziriro dzamasero dzinogadzirisa kuputsika kweDNA, dzinobvisa chidimbu chiduku cheDNA. Nenzira iyi, vanzveri vanogona kudzima nemazvo majini chaiwo ari mugenome. Chikwata ichi chakadzidza kugona kwechirongwa cheCRISPR/Cas9 kugadzirisa majini anonzi HBB anokonzera β-thalassaemia. Zvisinei, vamwe vanotaura kuti unyanzvi hwacho hungashandiswawo kubvisa zvirwere zvinokonzerwa nokugara nhaka zvakadai sechirwere chinonzi cystic fibrosis kana kuti mamwe marudzi ekenza. Vanzveri paSun Yat-sen University muGuangzho nhasi vakabudisa nzvero yavo mumagazini inonzi Protein & Cell, mukuwirirana nomushumo uri muNature. Muchinyorwa chacho, vaongorori vaitungamirirwa naJunjiu Huang, vakaedza kuderedza zvinonetsa nokushandisa ma"embryo" asina upenyu, asingagoni kukura kuva vana. Chikwata chacho chakaedza kuchinja majini anokonzera...
Masayendisiti echiChinese akaedza kuchinja majini anokonzera chirwere cheropa. Vanotsvakurudza vakakurumbira vakakumbira kumbomira kutsvakurudza kwakadaro kusvikira migumisiro uye kuchengeteka kworuzivo rwacho zvanyatsotsvakurudzwa. Vanonyevera kuti kugadziridzwa kwemutsetse wemabhonzo 'kune ngozi uye hakubvumirwi mutsika' Vamwe vanotya kuti unyanzvi hwacho hungashandiswa zvisiri izvo kuti vagadzire'mhuri dzomugadziri'
