Transcript of HARRY griffin

arry Griffin
Who is Harry Griffin ?
Director of the Roslin Institute

Dr Griffin graduated from Leeds University in l973 with an honours degree in Biochemistry.

He joined the Poultry Research Centre in 1978.
A. Harry Griffin
Cloning is a controversial subject.

According to Dr. Harry Griffin, “Clones are genetically identical individuals”.

“Twins are clones.“
Harry Griffin was knowledgeable of the technological flaws.

Cloning was still at a very early stage during griffin's time as Director of Roslin Institute

According to Dr. Griffin, cloning humans would simply be inefficient and unsafe.
Cloning (part 2)

There are three different ways of cloning:
Recombinant DNA technology or DNA cloning
Reproductive cloning
Therapeutic cloning (Nuclear Transfer)

Dolly, the cloned sheep, is the result of the reproductive cloning process.
Cloning (part 3)
Noun: a clone is an identical genetic copy of either a piece of DNA, a cell, or a whole organism.

Verb: "to clone" means to produce identical genetic copies of either pieces of DNA, cells, or whole organisms.
Definition of “Clone”
Cloning of plants has been a common practice of mankind for hundreds years.
The first cloning experiment dates back to over a hundred years ago in 1885. (Sea urchin)
Cloning of small animals also has a long history dated back to the 1960's.
The birth of Dolly was a major scientific and technological breakthrough.
Following the cloning of Dolly, many other animals have been successfully cloned.
Brief history of cloning
Griffin was very pro-cloning.

His view was to use cloning as a method to improve human life on earth.

Harry Griffin expressly declared human cloning would be excessively wasteful.

He believed that it would be right to clone humans if needed for reasons of infertility.
Harry Griffin’s thoughts on cloning
"Inefficient because in Dolly's case we used 277 reconstructed eggs to produce one successful pregnancy, collecting eggs from perhaps 40 donor ewes, and unsafe because a good proportion of our pregnancies fail late in pregnancy and we have had lambs that die soon after birth. (http://news.bbc.co.uk/2/hi/health/216034.stm)
Harry Griffin’s thoughts on cloning (2)
The process
The media began to accuse Harry Griffin of selling his research to major organisations.

It was also believed that these organisations would begin to make human clones.
What Harry Griffin wanted
Contrary to exaggerations of the media, Dr. Griffin’s only wish was for scientific gain, not monetary.

The idea of cloning a human was so complex that it seemed impossible, even to the scientists.
What Harry Griffin wanted (part 2)
In his mind, of course he wished that in the future they would be able to successfully clone a human but only for reasons of infertility.

Not only did he wish to be able to help people test medications to cure diseases, but he also wanted cloning to evolve so that the whole human race could gain from it too.
What Harry Griffin wanted (part 3)
It proved that differentiation of cells is reversible.

It showed that every cell contains the same genetic information.

Dolly was created in an effort to apply transgenic technology to the farming community.

It showed the obsoleteness of pro-nuclear injection.
Dolly’s importance
Technology serves a great purpose in almost every field of work.

With this development of technology comes innovations that are either regarded as inhuman or revolutionary.
The uses of cloning in the world of today

The uses of cloning in the world of today
Animals are used to determine and understand certain human diseases.

Mice are used in research of human diseases.

The breeding of mice is a slow trial and error method this could be solved by cloning.
Cloning in medicine
They are used to develop and repair the human body.

The cloning of these cells can help heal damaged organs.
Stem cells
To help produce more chemicals found in plants and animals, cloning can multiply the availability of food or drugs.
Animals and Plants
Cloning could be the solution to cure cancer

It can help with organ transplant

The problems with infertile people can be solved with cloning.
Cancer and infertility
Cloning leads to much more than creating an identical human; it may lead to many cellular discoveries.

If people do not like the concept of cloning, they can simply ignore it so it doesn’t affect their lives.
