Genomics The genetic analysis of entire genomes is called genomics. Such a broadscale analysis has been made possible by the development of recombinant DNA technology.

Besides studying the physical effects of cold exposure, the experimenters also assessed different methods of rewarming survivors.

After subjects were frozen, they then underwent different methods for rewarming. Many subjects died in this process. Many experiments were conducted on captured Russian troops; the Nazis wondered whether their genetics gave them superior resistance to cold.

The principal locales were Dachau and Auschwitz. Rascher had some of the victims completely underwater and others only submerged up to the head. Healthy inmates were infected by mosquitoes or by injections of extracts of the mucous glands of female mosquitoes.

After contracting the disease, the subjects were treated with various drugs to test their relative efficiency. The test subjects were injected with the disease in order to discover new inoculations for the condition.

These tests were conducted for the benefit of the German Armed Forces. Many suffered great pain in these experiments.

Therapeutic cloning produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues. Gene cloning, also known as DNA cloning, is a very different process from reproductive and therapeutic cloning. A brief history of cloning. Clone – in biology, a clone is defined as an organism having identical or nearly identical genetic material. Therefore, clones are not only the organisms obtained in the laboratory as a result of complex procedures, but also organisms created in the process of vegetative reproduction, such as bacteria. Cloning identical primates would decrease the genetic variation of research animals, and therefore the number of animals need in research studies. Similar to previous cloning experiments, Wolf’s team of scientists fused early-stage embryonic cells with enucleated monkey egg cells using a .

Test subjects were deliberately exposed to mustard gas and other vesicants e. Lewisite which inflicted severe chemical burns. The victims' wounds were then tested to find the most effective treatment for the mustard gas burns.

They were later executed. Infection was aggravated by forcing wood shavings and ground glass into the wounds. The infection was treated with sulfonamide and other drugs to determine their effectiveness.

Cloning - Genetics Generation

Sea water experiments From about July to about Septemberexperiments were conducted at the Dachau concentration camp to study various methods of making sea water drinkable. These victims were subject to deprivation of all food and only given the filtered sea water. Hans Eppingerleaving them gravely injured.

Tschofenig explained how while working at the medical experimentation stations he gained insight into some of the experiments that were performed on prisoners, namely those where they were forced to drink salt water.

Tschofenig also described how victims of the experiments had trouble eating and would desperately seek out any source of water including old floor rags. Tschofenig was responsible for using the X-ray machine in the infirmary and describes how even though he had insight into what was going on he was powerless to stop it.

He gives the example of a patient in the infirmary who was sent to the gas chambers by Dr. Sigmund Rascher simply because he witnessed one of the low-pressure experiments. The law was used to encourage growth of the Aryan race through the sterilization of persons who fell under the quota of being genetically defective.

Within 4 years,patients had been sterilized. The targets for sterilization included Jewish and Roma populations.

Thousands of victims were sterilized. Aside from its experimentation, the Nazi government sterilized aroundpeople as part of its compulsory sterilization program.

Specific amounts of exposure to radiation destroyed a person's ability to produce ova or sperm, sometimes administered through deception. Many suffered severe radiation burns. Seidelman, a professor from the University of Toronto, in collaboration with Dr. Howard Israel of Columbia University published a report on an investigation on the Medical experimentation performed in Austria under the Nazi Regime.

In that report he mentions a Doctor Hermann Stieve, who used the war to experiment on live humans. Stieve specifically focused on the reproductive system of women.

He would tell women their execution date in advance, and he would evaluate how their psychological distress would affect their menstruation cycles.A brief history of cloning. Clone – in biology, a clone is defined as an organism having identical or nearly identical genetic material.

Therefore, clones are not only the organisms obtained in the laboratory as a result of complex procedures, but also organisms created in the process of vegetative reproduction, such as bacteria. The history of genetics dates from the classical era with contributions by Hippocrates, experiments pointed to DNA as the portion of chromosomes (and perhaps other nucleoproteins) American and British scientists unveiled a technique for testing embryos in-vitro (Amniocentesis).

Invention of recombinant DNA technology The History of Cloning The History of Cloning Lost in the midst of all the buzz about cloning is the fact that cloning is nothing new:
Early cloning experiments Jan 1, Charles Darwin Joint announcement of the theory of natural selection-that members of a population who are better adapted to the environment survive and pass on their traits. It is a work of scientific literature which is considered to be the foundation of evolutionary biology.
1902 - Artificial embryo twinning in a vertebrate The model is not fully symmetric.

Molecular cloning is a process by which scientists amplify a desired DNA sequence. The target sequence is isolated, inserted into another DNA molecule (known as a vector), and introduced into a suitable host cell.
