Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: I hangaia a Zhong Zhong me Hua Hua e nga kaiputaiao mai i te Institute of Neuroscience o te Chinese Academy of Sciences i Shanghai, i arahina e Qiang Sun me Muming Poo. I tangohia e rātau ngā karihi mai i ngā fibroblasts o tētahi mokopuna i whakakorehia (he macaque kai karepe, Macaca fascicularis rānei) a ka whakauruhia ki roto i ngā pūtau hua manu (ova) i tangohia ai ōna ake karihi. I whakamahia e te rōpū e rua ngā whākōkī hei whakakore i te pūmahara epigenetic o ngā karihi i whakawhitihia hei pūtau somatic. Na tēnei taahiraa nui o te whakarerekētanga i āhei ai ngā kairangahau ki te wikitōria i te ārai nui i ārai i te angitu o te whakakotahitanga o ngā kararehe tae noa ki tēnei wā. I whakanohoia e rātau 21 o ēnei hua ki roto i ngā māmā whakakapi, e ono ngā hapūtanga i puta, e rua o ēnei i puta mai he kararehe ora. Ko nga monkey i tapaina ko Zhong Zhong me Hua Hua, he tohutoro ki Zhonghua (Chinese, he ingoa Hainamana mo Haina). Ahakoa he iti tonu te auau angitu, ka taea te whakapai ake i nga tikanga hei whakanui ake i te reanga ora i roto i te heke mai. Hei whakataurite, i hiahiatia e te rōpū i Scotland i waihanga i a Dolly te hipi i te tau 1996 e 277 ngā whakamātau, ā, kotahi noa iho te reme i whakaputaina. I whakamātau hoki ngā kaipūtaiao ki te tārua i ngā kākano mā te whakamahi i ngā karihi mai i ngā kaiwhiwhi pakeke, he uaua ake. E 42 ngā kōtiro i whakanohoia ki roto, ā, 22 ngā hapūtanga, engari e rua noa iho ngā kōtiro kōtiro, ā, i mate rātau i muri tata iho i te whanautanga.  Pātai: He aha te momo kararehe i ngana ai ngā kairangahau ki te tāruatia?
