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.
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
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
Different forms of the same gene are called alleles. A genetic locus is the spot on the chromosome where alleles for a specific gene can be found. Diploid organisms, including humans, have two alleles at each genetic locus because they inherit one allele from each parent.
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.
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
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.
Action therapy, also called action-oriented therapy, is a form of psychotherapy that focuses on practical solutions to mental health problems. Cognitive-behavioral therapy is one of the most commonly used forms of action therapy.
