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 ge... More » Science Biology Cells

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 ... More »

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’... More »

Gene cloning occurs when a specific gene from a strand of DNA has been extracted and copied from an organism. Nearly any tissue source can be used for cloning, as long as there is not widespread degradation. DNA can also... More »

Gene splicing is a technique used in genetic engineering where the DNA of a living thing is edited, in some cases replacing existing genes with genes taken from another plant or animal. Enzymes are used to cut the DNA st... More »

Different or alternative forms of the same gene are called alleles. Individuals receive two copies of each gene, one from each parent. Alleles can be either dominant or recessive. More »
