Pair Work Read para1-3 and answer the questions in pairs. 2 What examples of natural cloning are given For example,gardeners have been using a formof cloning when they take a cutting from a plant and place it in a suitablemedium,such as soil.Another example of natural cloning is identicaltwins,who are produced from the same egg. Pair Work Read para1-3 and answer the questions in pairs. 3 What was the first cloned mammal What happened to her Dolly. She developed an illness that is more normally found in much older animals. She only lived for six and a half years,only half the life of the sheep from which she was cloned. Pair Work Read para1-3 and answer the questions in pairs. 4 How has the science of cloning developed since the first cloned mammal After Dolly, scientists have cloned more than 20 mammal species. However, they have found a similar pattern of health problems with other species as well. Pair Work Read para1-3 and answer the questions in pairs. 5 What development in cloning was announced in 2018 What was special about it Chinese scientists cloned two long-tailed monkeys in January 2018. They were the first-ever primates to have been cloned . Pair Work Read para1-3 and answer the questions in pairs. 6 For how long did Dr.Sun Qiang's team work Why did they work so hard They had been taking care of more than 1,000 monkeys 24 hours a day, 7 days a week for 5 years. In order to break this technical barrier 1. What is cloning 2. What examples of natural cloning are given 3. What was the first cloned mammal What happened to her Cloning is the process of making an exact copy of a plant or animal and developing it naturally and artificially. An example of natural cloning is taking a cutting from a plant and putting it in soil, and another is identical twins. The first cloned animal was Dolly the sheep. She develope ... ...
