The Applications of Biotechnology
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
Cloning AnimalsCloning and Genetic Engineering in Animals
Genetically Engineered AnimalsCloning and Genetic Engineering in Animals
How to Clone
Nuclear transfer procedures
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
An Organism can be cloned by transferring it’s DNA to an egg cell

Genetically Modified somatic nuclei could be implanted into unfertilized eggs to create a genetically modified clone

Transgenics and Cloned Animals
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
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
Principle• All cells are derived from a zygote
• All have the same genetic makeup
• All have the potential to develop into an individual

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
(B) that all of the DNA that codes for an entire organism is in every cell of that organism (C) 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

Cells from an amniocentesiscan 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.

I would clone myself if that were possible.
(A) yes(B) no (C) undecided
The Possibilities of Human Cloning
To Clone or Not to Clone
