  1. Objective: Learn the Process of Cloning and What the Benefits and Concerns Are New Words: clone, cloning, embryo, donor organism, foster organism • DO NOW: • List 3 things you have learned about Selective Breeding Dolly

  2. Objective: Learn the Process of Cloning and What the Benefits and Concerns Are New Words: clone, cloning, embryo, donor organism, foster organism 1. What do you already know about “Cloning”? Dolly

  3. Objective: Learn the Process of Cloning and What the Benefits and Concerns Are New Words: clone, cloning, embryo, donor organism, foster organism 2. What exactly is Cloning? Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two! http://learn.genetics.utah.edu/content/tech/cloning/clickandclone/ Dolly

  4. A donor cell is taken from a sheep’s udder. Donor Nucleus These two cells are fused using an electric shock. Fused Cell Egg Cell The nucleus of the egg cell is removed. An egg cell is taken from an adult female sheep. The fused cell begins dividing normally. Embryo Cloned Lamb The embryo is placed in the uterus of a foster mother. The embryo develops normally into a lamb—Dolly Foster Mother Objective: Learn the Process of Cloning and What the Benefits and Concerns Are New Words: clone, cloning, embryo, donor organism, foster organism 3. Arrange the following steps in order from 1 through 7. 6 • The fused cell begins dividing, becoming an embryo. ____________ • The embryo develops into a cloned animal ____________________ • An egg cell is taken from a donor animal ______________________ • The embryo is implanted into the uterus of a foster mother. _______ • The body cell and egg are fused by electric shock. ______________ • A body cell is taken from a donor animal ______________________ • The nucleus is removed from the egg. ________________________ 7 2 5 4 1 3

  5. Objective: Learn the Process of Cloning and What the Benefits and Concerns Are New Words: clone, cloning, embryo, donor organism, foster organism 4. Is it Cloning? Or not? Test your cloning savvy with this interactive quiz. http://learn.genetics.utah.edu/content/tech/cloning/cloningornot/ Dolly

  6.

  7. Objective: Learn the Process of Cloning and What the Benefits and Concerns Are New Words: clone, cloning, embryo, donor organism, foster organism a. What is a clone? 3. List two benefits of cloning: 4. List two concerns of cloning: 5. What kinds of mammals have been cloned in recent years? 6. Why do not scientists clone humans? A member of a population of genetically identical cells produced from a single cell a) It may help to save endangered species b) It makes copies of transgenic animals • Cloned animals may suffer from a number of genetic defects • Cloned animals may have health problems Sheep, cows, pigs, mice, horse,… Many people oppose the cloning of humans because ethical, moral, and religious reasoning

  8. Objective: Summarize the main ideas about Cloning New Words: clone, cloning, embryo, donor organism, foster organism Name of the Technique CLONING Brief description of what is involved in the technique Specific examples of how this technique has been used How humans have benefited from this technique What are the concerns?

  9. Objective: Summarize the main ideas about Cloning New Words: clone, cloning, embryo, donor organism, foster organism Name of the Technique CLONING Brief description of what is involved in the technique process of producing genetically identical individuals Specific examples of how this technique has been used Sheep, cows, pigs, mice, horse, etc. have been cloned How humans have benefited from this technique a) It may help to save endangered species b) It makes copies of transgenic animals What are the concerns? • Cloned animals may suffer from a number of genetic defects • Cloned animals may have health problems

  10. Objective: Practice Regent’s Questions about Cloning New Words: clone, cloning, embryo, donor organism, foster organism 1. From a single monkey, an animal breeder claims that he has successfully cloned two monkeys. He displays the two monkeys, a male and a female, to the public. The claim of the breeder should be rejected because 2. Write a paragraph in which you express you opinion about cloning human beings. The two monkeys are not genetically identical, they show different sex genders.
