(40 points)Text 1 Chinese scientists recently have produced two monkeys with the same gene，Zhong Zhong and Hua Hua，using the same technique that gave us Dolly the sheep. These monkeys are not actually
9、the first primates（灵长目动物）to be cloned. Another one named Tetra was produced in the late 1990s by embryo splitting（分裂），the division of an early-stage embryo into two or four separate cells to make clones. By contrast，Zhong Zhong and Hua Hua were each made by replacing an egg cell nucleus（细胞核）with DNA
10、 from a different body cell. This Dolly method，known as somatic cell nuclear transfer（SCNT），can create more clones and allows researchers greater control over the edits they make to the DNASuccess came from adopting several new techniques. These included a new type of microscope to better view the c
11、ells during handling or using several materials that encourage cell reprogramming，which hadnt been tried before on primates. Still，the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys were born from more than 60 tested mothers. This led to many r
12、esearchers pouring water on the idea that the teams results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too ineff
13、icient, far too unsafe, and it is also pointless.But the scientists involved emphasized that this is not their goal. There is now no barrier to cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely to produce non-human primate models for human
14、 diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough as a novel model system for scientists studying human biology and diseases.1、What do we know about the technology called SCNT?AIt created th
