Answers of the listening on "Cloning"

Ok! Here we are..! Hi guys! I’ve been working for hours to do this homework but finally I’ve done it! =)

1. What are the main types of cloning? The main types of cloning are: reproductive cloning, where a new baby will be created and therapeutic cloning, where only some of the cells will be copied.


2. What is the aim of stem cells into the body? Stem cells regenerate tissue: they replace cells that are lost through natural processes.
   


3. What are scientists actually studying? Scientists are studying the possibility of treating certain diseases such as Parkinson, hearth disease or disease of the brain by introducing new stem cells into the body; embryo cells are the centre of much of the current research.
   


4. How was the sheep Dolly created? The sheep Dolly was created trough cloning: a nucleus taken from an adult sheep cell was inserted into an empty egg.
   


5. Why would therapeutic cloning be useful? Therapeutic cloning can solve reject problems in organ transplants.
   


6. What does Professor Gardner think would be possible in the future? Professor Gardner thinks it may be possible to extract the nucleus of a cell from the patient to briefly clone an embryo of him and then to use the embryo stem cell to treat him. In future this method could even be used to create a personalized bank of stem cells that can be stored and used when the patient needs them.
   


7. What kind of ethical dilemmas are the governments facing? The governments are facing such ethical dilemmas: should scientist be allowed to harvest stem cells from embryos? Should the cloning of human embryos be permitted?
   


8. In Britain what is the limit of time research? In Britain the research is permitted on embryos up to fourteen days old.
   


9. What is Professor Donaldson’s opinion on the cloning research? Professor Donaldson thinks that the creation of a human being through cloning should not be permitted under any circumstances. It’s illegal at the moment and should remain illegal.
   


10. Why is not possible in certain states to make research of embryos? In certain states the research on embryos is not possible because an embryo, however young, is considered a human being. Embryo has the potential to become a human being.
