Gene therapy is an experimental technique performed by replacing a mutated gene with a healthy copy of the gene as an alternative to surgery or medications. It is designed to make a beneficial protein or introduce new genes to mutated cells to compensate for a patient's abnormal genes, explains Gene
According to Genetics Home Reference, gene therapy requires the use of healthy genes to treat illnesses. Instead of a person undergoing surgery, genes are introduced to a patient's body to replace corrupted DNA. Another method is to inactivate negative genes instead of replacing them.
Though still experimental, gene therapy fixes genetic defects and potentially reduces the need for drugs, radiation or surgical intervention. Replacing bad genes with good ones may eventually cure Parkinson’s, Alzheimer’s, cancer and many other diseases.
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.
Genes that occur at the same place on the chromosome but occur in different forms are called alleles. Alleles are essentially different versions of a gene, and they can cause dissimilarities in an organism's function or structure. An example is the gene responsible for melanin production in most ani
Because stem cell therapy is in its infancy, its safety in all potential uses hasn't been fully studied. However, early studies in which stem cell therapy were used to treat macular degeneration proved to be safe three years after the procedures were performed, WebMD reports.
Genes carry the information necessary to synthesize proteins, which are manufactured in the organelles surrounding the nucleus of a cell. Specialized sections of RNA transcribe the instructions from the genes and carry them out to the cell for production.
Genes, which are segments of DNA acids, are found within the nuclei of cells in living organisms. Genes add specific proteins to chromosomes, which contain the basic genetic code for life. They contain the information needed to build the cells of a living organism and pass traits to offspring. Genes
Wilhelm Johannsen coined the term "gene" in 1909. However, before him came scientists such as Gregor Mendel, Hugo de Vries, Carl Correns and Erich von Tschermak who all developed theories on inheritance patterns in plants. They all understood that traits could be inherited, but they did not visualiz
Also referred to as gene migration, gene flow is the introduction of genes from one population to the gene pool of another population. This process changes the composition of the gene pool of the receiving population. Good examples of gene flow include the movement of pollen grains from one plant to
