Gene therapy is a treatment that revolves around altering the genes inside cells to stop disease, according to Mayo Clinic. The pros include helping people fight disease or even cure their disease, while some cons are unwanted immune reactions, infections, tumors and damaging healthy cells.Know More
Researchers are looking at several ways to use gene therapy, including replacing or fixing mutated genes and making diseased cells easier targets for the immune system, explains Mayo Clinic. Replacing genes that don't work correctly or no longer work at all may help treat certain diseases. Mutated genes could be turned off so they don't promote disease, and healthy genes could be turned on so they inhibit disease. Gene therapy could be used to train the immune system to better recognize cells that are a threat.
Because the new genes are delivered using a carrier that is usually a virus, the immune system might attack them and cause inflammation or organ failure, notes Mayo Clinic. It's possible the viruses may infect additional cells, and if this happens healthy cells could be damaged, causing other diseases, including cancer. Although they're altered before insertion, the viruses might recover their ability to cause disease once introduced into the body. If new genes get inserted in the wrong spot it could lead to tumor formation.Learn more in Molecular Biology & DNA
Supporters of DNA fingerprinting argue that the process makes it easier and more efficient for police to solve crimes. Critics claim that DNA fingerprinting is invasive and violates citizens’ right to privacy.Full Answer >
The GFP gene is a gene from the jellyfish Aequorea victoria that encodes a green fluorescent protein. GFP was isolated from the jellyfish in 1994 and is now a commonly used biological marker in genetic engineering experiments.Full Answer >
A DNA microchip or gene chip is a tiny chip that has many single strands of the DNA from a specific gene attached to it. Sometimes a microchip has more than one gene's DNA on it or different variations of a gene. It is used to test for gene mutations, such as the ones that are thought to be responsible for a larger percentage of hereditary breast cancer cases.Full Answer >
The lacZ gene is a gene present in E. coli that encodes the protein beta-galactosidase. Beta-galactosidase is an enzyme that is essential for the breakdown of lactose as it cleaves a bond between the two carbon rings in lactose to produce glucose and galactose.Full Answer >
