2、when their loving pet passes away.Why not make a clone of that dog then？This is the solution offered by a South Korean company, Sooam Biotech Research Foundation.The company has successfully cloned at least 400 dogs, mostly for US.customers, ever since it pioneered the technique in 2005.Now, Sooam B

3、iotech is planning to introduce their business to UK.dog owners, offering them dogs that look just like their lost ones.Meanwhile, another dog is selected to supply an egg.Researchers then replace the DNA in the egg with that from the skin cell and implant the egg into the womb (子宫) of a female dog.

4、The egg grows into a puppy over the following two months.To clone a dog, researchers first need to take a skin cell from a living dog or one that has just died.The whole process takes less than a day, but it comes at a shockingly high price, around 63,000 (614,000 yuan)But if you cant afford it now,

5、 you can also save the cells in a laboratory and access them at a later date.Just like identical twins of humans, they share the exact same DNA but there will still be small differences between them.“The spots on a Dalmatian clone will be different, for example， ”Insung Hwang, head of Sooam Biotech,

6、 told The Guardian.However, as magical as cloning might sound, there is no guarantee that the cloned dog will be a perfect replica (复制品) of the original one.Dog owners will also have to accept the fact that personality is not “cloneable”Apart from genes, personality is also determined by upbringing

14、ortsCis afraid of Dis curious about解析：推理判断题。根据文章最后一段可知，柯克伍德指出，在人与宠物之间的关系中，最重要的一方面就是处理好它们离去所带来的痛苦。最后一段第一句也提到，也许用克隆的方式把宠物留在身边不是纪念它们的最好方法。由此可推测，柯克伍德是反 对克隆狗的。故选 A 项。B(2016郴州市一模) 导 学 号 42492788Scientists in Argentina have created the worlds first cow to own two human genes that will enable it to produce
