Why is the offspring of asexual reproduction a clone?
KEY CONCEPT DNA sequences of organisms can be changed.

2. Click and Clone Questions
Please copy down the questions on p.18. Leave room for the answers.
Click and Clone Questions
What two types of cells do you need in order to create a clone?
How many organisms does it take to make a clone?
Which two mice will be genetically identical?
Will the clone always look and act identical to its genetic donor?

3. KEY CONCEPT DNA sequences of organisms can be changed.
CC= Copy Cat or Carbon Copy

4. Entire organisms can be cloned.
A clone is a genetically identical copy of a gene or of an organism.
Born Dec 22, 2001 after 86 unsuccessful tries
CC- The first cloned cat

5. Cloning occurs in nature:
bacteria (binary fission- makes a copy of itself)
some simple animals and plants (budding, regeneration)
Identical twins

6. Planaria- “Regeneration”
Planaria can be cut into pieces, and each piece can regenerate into a complete organism.
Cells at the location of the wound site regenerate the missing parts
It's this feature that gave them the famous designation of being "immortal under the edge of a knife."  
Very small pieces of the planarian, estimated to be as little as 1/279th of the organism it is cut from, can regenerate back into a complete organism over the course of a few weeks.

7. Mammals can be cloned through a process called nuclear transfer.
TRANSFERRING of a NUCLEUS

8. 1. Nucleus is removed from the egg cell of a donor female

9. 2. nucleus of a somatic (body) cell from the animal to be cloned is implanted in the donor egg
Skin cell

10. 3. Electricity or special chemicals are used to stimulate the egg to begin division leading to the development of an embryo
* NO SPERM in cloning

11. 4. The embryo (blastocyst) is then implanted into a surrogate mother

12. 5. (Human) Clone will then take 10 months (40 weeks) to gestate

13. 6. Clone will be born

No. The behavior may be very different from the original.

18. Review

19. Dolly and her lamb Bonny
MEET DOLLY
In 1996 Dolly became the first mammal to be cloned using an adult somatic (body) cell. She was born on the 277th try.
Dolly and her lamb Bonny
Did you know?
She was derived from a mammary gland
She was named after Dolly Parton

20. Issues with Dolly
She developed and grew normally, but she had health problems
Did not live as long as typical sheep

21. Known animals to have been cloned as of 2012:
Carp (fish)
Cat
Pig
Cattle
Pyrenean ibex (type of goat)
Deer
*first extinct animal to be cloned- only lived 7 mins
Dog
Ferret
Rabbit
Frog (tadpole)
Rat
Fruit Flies
Rhesus Monkey
Gaur (wild cattle)
Sheep
Goat
Water Buffalo
Horse
Wolf
Mice
Mouflon (wild sheep)
Mule

22. Benefits
Maybe use organs from cloned mammals for transplant into humans saving millions of lives
save endangered species by increasing population #s
Concerns
low success rate (approx. 1-3 % are successful)
clones “imperfect” and less healthy than original animal
decreased biodiversity because the clones would be genetically identical to other organisms in the community

23. Pet owners expecting to clone an exact copy of their furry friend will be disappointed…
*CC does not have the health issues normally associated with other clones.
May not look, act, or behave like the original. Likely to have health issues, and a shorter life span.

Essential Question: Why do so many people oppose both reproductive and therapeutic cloning?
9.4 Types of Cloning
2.1 Atoms, Ions, and Molecules
Why do so many people oppose both reproductive and therapeutic cloning?

26. Ethics Involved in Cloning
Ethics: the branch of knowledge that deals with moral principles
What are some ethical principles that we must consider when cloning?

28. Therapeutic vs. Reproductive Cloning
Reproductive cloning: involves creating an animal that is genetically identical to a donor animal through somatic cell nuclear transfer.
(In reproductive cloning, the newly created embryo is placed back into the uterine environment where it can implant and develop)
Dolly the sheep is perhaps the most well known example.

29. Therapeutic vs. Reproductive Cloning
Therapeutic cloning: an embryo is created in a similar way, but the resulting "cloned" cells remain in a dish in the lab; they are not implanted into a female's uterus
Sole purpose: To create stem cells with the same DNA as the donor cell
Used to understand disease/developing new treatments
***Embryo will be destroyed

30. Therapeutic vs. Reproductive Cloning

31. Cloning in movies and books
The Island (2005)
People on the island are told what to eat, wear, and how to act.
They are clones. Held prisoner to be used for spare parts or as surrogates

41. Open your biology book to page 225, and on the top section of pg
Open your biology book to page 225, and on the top section of pg. 22 write a paragraph explaining how genetic engineering is responsible for making this mouse glow.

42. The mouse’s green glow comes from the green fluorescent protein GFP
The mouse’s green glow comes from the green fluorescent protein GFP. Scientists put a gene from a glowing jellyfish into a virus that was allowed to infect a mouse egg. The jellyfish gene became part of the mouse’s genes. As a result the mouse cells produce the same protein.

43. Table Talk
What do you think genetic engineering involves?
Examples?
What sorts of things can we genetically engineer?
Plants
Animals
Bacteria

44. Genetic engineering involves changing an organism’s DNA to give it new traits by inserting cloned genes from one organism into a different organism.
Possible because the genetic code is shared by all organisms (all living things share the same 4 nucleotides A,T,C,G)

45. Draw/label/ color code on pg. 23
Genetic engineering uses Recombinant DNA (think re-combination) which is DNA that contains genes from more than one organism.
Bacterial plasmids are often used to make recombinant DNA.
Plasmids are closed loops of DNA found in bacteria
Foreign DNA
Recombinant DNA
Plasmid from bacterial cell
Original DNA
Draw/label/ color code on pg. 23

46. 1. Restriction enzymes cut plasmid and foreign DNA
2. foreign gene inserted into plasmid
3. Plasmid put back into bacteria
4. Bacteria will multiply
*Result: New proteins will be expressed in the bacteria!

47. Designing Genes 2m44s

48. Genetic engineering produces organisms with new traits!
A transgenic organism has one or more genes from another organism inserted into its genome.

49. TRANSGENIC ORGANISMS
Transgenic
Bacteria
Transgenic
Plants
Transgenic
Animals
What are they produced for?
Real life Examples of each

50. Transgenic bacteria can be used to produce many useful chemicals
Cancer drugs
Pesticides
Insulin
*Ex: Insulin is made by introducing human recombinant DNA into a plasmid allowing it to multiply
It is then collected and used to treat people with diabetes

51. *Bacteria used to produce artificial sweeteners
Aspartame- Widely used artificial sweetener
Diet soda
Sugar-free gum and candy
Sugar-free desserts
Sugar-free condiments

52. Transgenic plants
transgenic bacteria infect a plant
many crops are now genetically modified(GM)
Ex: resistance to frost/diseases/insects
***In order for plants to “pass down” the genetic trait to their offspring they must be sure that the gene is present in the seed of the plant!***

53. Farmers use pesticides to get rid of “pests”
Farmers use herbicides to get rid of weeds
If we spray a “herbicide” on a crop full of weeds what might happen?
Scientists have developed genetically engineered plants that are resistant to the herbicides

54. Manipulating Plant Genes 2m25s

55. Genetically Modified Food (Docu) UK 13m15s

56. Transgenic animals are used to study diseases and gene functions.
*The hope is to treat/cure diseases in humans
Hard to produce!
Must get a fertilized egg-insert the foreign DNA back into female
Only a small % of these will mature normally
Only some will be transgenic

57. The animals that are transgenic will have the foreign gene as part of their DNA
*Gene will be in ALL of their cells, including the sperm/egg, and therefore they can pass it on to their offspring

58. Manipulating Animal Genes 1m43s

How do the Jurassic Park scientists manipulate the dinosaur DNA to make transgenic dinosaurs?
What type of egg do they use to allow the dinosaurs to develop in? (Very quiet, in the background)
Do we need a surrogate?
Why were the dinosaurs unable to breed?

61. Why does John need a drop of blood from John?
To extract DNA from
What is inaccurate about the cloning of John?
A real clone would not be the same age, it would be a baby
How do the Jurassic Park scientists manipulate the dinosaur DNA to make transgenic dinosaurs?
They fill in the “gaps” in the dinosaur DNA with frog DNA
What type of egg do they use to allow the dinosaurs to develop in? (Very quiet, in the background)
They use unfertilized ostrich eggs (This is why there is no need for a surrogate.
Do we need a surrogate?
No. Just the egg donor (ostrich) and DNA from the animal
Why were the dinosaurs unable to breed?
They were all female.

62. Concerns with Genetic Engineering
Scientists have concerns about some uses of genetic engineering.
Possible long-term health effects of eating GM foods
Possible effects of GM plants on ecosystems and biodiversity (will they kill other organisms)
Ex: GM plants- side effect- kill certain insects
Other unknown side effects?????
cause allergies/cancer?
