GENE THERAPY Gene therapy is when scientist use genetic engineering to correct some genetic disorders in humans. The most common form of gene therapy involves using DNA from a functional gene to replace a mutated gene. GENETIC ENGINEERING Genetic engineering produces organisms with desired traits. This happens when genes from one organism are transferred in the DNA of another organism. Genetic engineering can produce medicines and improve food crops. ADVANCES
GENETICS THE HUMAN GENOME PROJECT A genome is all the DNA in one cell of an organism. DNA FINGERPRINTING DNA Technology used in the Human Genome Project can also identify people and show whether people are related. DNA from a person's cells is broken down into smaller fragments. Selected fragments are used to produce a pattern called a "DNA FINGERPRINT". DNA FINGERPRINTING Genetic engineering produces genetic modified food (GMO). Some foods that are genetically modified are prone to faster production, extra nutrients and less pathogens. Controversy: the public is concerned about the lack of labels on this GMOs. Some people are concerned about the long terms affect of GMOs and that tampering with nature will have future ramifications. Others feel that there is a distinct taste difference between GMOs and non-modified foods. The main goal of of the Human Genome Project has been to identify the DNA sequence of every gene in the human genome. Scientists have learned that the DNA of humans has at least 30,000 genes. The average gene has about 3,000 bases . The human genome was mapped by a company named Celera in 2003. HOW DOES IT WORK?
It's a little complicated...but let's give it a try! STEM CELLS A stem cell is essentially a “blank” cell, capable of becoming another more differentiated cell type in the body, such as a skin cell, a muscle cell, or a nerve cell. Why is there such an interest in stem cells?

Researchers hope stem cell studies can help to:

Increase understanding of how diseases occur. By watching stem cells mature into cells that eventually become bones, heart muscle, nerve cells, and other organs and tissue, researchers and doctors may better understand how a variety of diseases and conditions develop. Researchers hope they can train stem cells into becoming specific cells so that those specialized cells can be used to regenerate and repair diseased or damaged tissues in people. People who might benefit from stem cell therapies include those with:
spinal cord injuries, type 1 diabetes, Parkinson's disease, Alzheimer's disease, heart disease, stroke, rheumatoid arthritis, osteoarthritis and multiple sclerosis. Stem cells could also be grown to become new tissue for use in transplant medicine.
