Transcript of Genetic Engineering
The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity.
What types of cloning are there?
How are genes cloned?
How are animals cloned
What has been cloned so far?
What are the potential applicatioons for cloning animals?
Gregor Mendel's publicized his discoveries on the breeding of peas which became the foundation of

The birth of the
first cloned animal
, Dolly the sheep, was announced.
UK Parliament passes a regulation believed to allow the cloning of human embyos for the purposes of research into serious disease. May be experimented on only up to their 14th day of life.

HISTORY TIMELINE OF GENETIC ENGINEERING
Do you think it is ethically acceptable to clone animals? What about humans?
Has society become more supportive or less suportive genetic engeneering?
Does designing your own baby make people too "God" like?
Is there anything we didn't cover that you would like to discuss?

in Popular Culture
The Pros of Designer Babies
Reduces risk of genetic diseases
Reduces risk of inherited medical conditions
Keep pace with others doing it
Better chance the child will succeed in life
Better understanding of genetics
Increased life span
Can give a child genes that the parents do not carry
Prevent next generation of family from getting characteristics/diseases
The Cons of Designer Babies
Termination of embryos
Could create a gap in society
The increased ability to control and manipulate embryos presents many possibilities for improving the health of children through prenatal diagnosis, but these possibilities are coupled with potential social repercussions that could have negative consequences in the future.
Possibility of damage to the gene pool
mistakes in placing certain genes in the wrong spot.
Baby has no choice in the matter
Genes often have more than one use
Geneticists are not perfect
Loss of Individuality
Other children in family could be affected by parent's decision
Only the rich can afford it
What is it?
A para-human is a human-animal hybrid (or chimera), which is an entity that incorporates genetic elements from both humans and non-human animals.
Why is it Important?
“More than 123,000 people in the United States currently need an organ transplant, and about 21 people die each day waiting for one."
- U.S. Department of Health and Human Services
Pros & Cons
Because of the prohibition on human cloning proposed by President George Bush in 2006, para-human research is illegal in America.
It is outlawed in Japan, but is gaining widespread support. Scientists and researchers have already been experimenting.
This will be able to save human lives, and require less people to be organ donors.
First human-animal chimeras to actually exist were first created by Shanghai Second Medical University Scientists.
