Understanding of Clone Definition of Cloning examples of natural cloning are given First cloned mammal Cloning is the process of making an exact copy of a plant or animal anddeveloping it either naturally or artificially. Gardeners have been using a form of cloning when they take a cutting from a plant and place it in a suitable medium. Another example of natural cloning is identicaltwins, who are produced from the same egg. Dolly the sheep (1996, Scotland) 13 While-reading Activity 2: Read paragraphs 3 Answer the questions. 1.What development in cloning was announced in 2018? 2.What was special about it? 3.

Potential benefits Moral concerns will lead to cures forvarious diseases has refreshed the technicalpossibility of cloning of other species offer clues on how to prevent the aging process could help save research time, reduce the number of animals required for tesing, produce more acurate results,and lead to more effective treatments be treated as objects or as individuals with their own identity may be viewed as mere copies of originals thus being seen as inferion some organisations may abuse the technology for unethical purposes 15 While-reading Activity4 :Read part 2 to compare the information. first successful cloned animal first-ever cloned primates name:____________ time:____________ problems:_________________ influence:____________________ name:_____________________ time:_______________________ special part:______________________ reasons of doing this:___________________________ VS Dolly in 1996 developed an illness; lived only half the life of the sheep she was cloned. Scientists have cloned more than 20 mammal species. Zhong Zhong & Hua Hua In Jan.2018 much harder/ more complicated Get animals with edited genes and produce animal models that are helpful for medical research and human health. 16 While-reading Activity: Read the last paragraph and answer the questions. What does Einstein's quote mean? Einstein’s quote means that science itself cannot be judged as good or bad, because it can only function when it is used by humans. He also indicates that humans need to be careful with the information they learn through science and to remember to use science for good. 17 Post-reading 04. 18 Post-reading Pair Work Explain Cloning to Your Partner 1.
