4
Where is DNA in a cell? All of the information for each protein in a cell is in it’s DNA All of the information that codes for a complete organism is in DNA
5
Cloning Animals Cloning and Genetic Engineering in Animals
6
Genetically Engineered Animals
Cloning and Genetic Engineering in Animals
7
How to Clone
8
Nuclear transfer procedures
9
An Organism can be cloned by transferring it’s DNA to an egg cell
This shows: All of the information that codes for an organism is in it’s DNA All of the DNA is the same in every cell DNA is located in the nucleus of the cell
10
Could we Genetically Engineer Cloned Animals? Controlled expression
Promoter Coding Sequence Terminator Your favorite gene Vaccines Antibodies High Value Proteins Spider Silk in Goats Milk Controlled expression “making protein” Stop transcription Message stability
11
Genetically Modified somatic nuclei could be implanted into unfertilized eggs to create a genetically modified clone
12
Transgenics and Cloned Animals
Genetically Modified somatic nuclei could be implanted into unfertilized eggs to create a genetically modified clone
13
What is cloning? A process whereby all members are directly descended (asexually) from a single organism by……(various ways) Demonstrates that all the information required for an organism and its development are in the a single cell
14
Where is DNA in a cell? All of the information for each protein in a cell is in it’s DNA All of the information that codes for a complete organism is in DNA
16
Principle All cells are derived from a zygote
All have the same genetic makeup All have the potential to develop into an individual

FIGURE 5-45 Genetically identical cloned animals. The cloning of animals can maintain desirable traits from generation to generation.
24
Many animals can now be cloned And Genetically Engineered sheep cattle
porcine mice rats mules frogs primates? And Genetically Engineered
25
Primates Many animals can now be cloned And Genetically Engineered
2012 And Genetically Engineered
27
Issues in Biotechnology
The ‘cloning’ of plants was demonstrated by Steward in 1958 at Cornell Univ. showing that plants could be grown back from a single cell. This ability is called “totipotency” and like the more recent examples of animal cloning, demonstrates: (A) that all biological scientists are unethical and fraudulent that all of the DNA that codes for an entire organism is in every cell of that organism Steward belonged to the group that called themselves the ‘Raeliens’ (D) the necessity to ban all types cloning (E) that the theory of evolution must be wrong
28
Could we Genetically Engineer Humans? Controlled expression
Promoter Coding Sequence Terminator Your favorite gene Insulin Cancer Anti-Oncogenes Parkinson’s Huntington’s SCID Beyond Therapy??? Controlled expression “making protein” Stop transcription Message stability
29
Can humans be cloned and/or genetically engineered?
Cells from an amniocentesis can be used for DNA sequence analysis. All of the genes for humans will be known. Disease genes would be detected. Cloned “correct” genes could be used for replacement. Corrected nucleus could be delivered to an unfertilized egg. Same baby without the defect.

Could we Genetically Engineer Humans?
31
The Tay Sachs Dilemma
32
Do You Think We Should We Genetically Engineer Humans?
(A) yes (B) no (C) depends on the circumstance
33
Issues in Biotechnology
I would clone myself if that were possible. (A) yes (B) no (C) undecided
34
The Possibilities of Human Cloning
35
To Clone or Not to Clone
