How can you alter an organism's genes
WebGene therapy seeks to alter genes to correct genetic defects and thus prevent or cure genetic diseases. Genetic engineering aims to modify the genes to enhance the capabilities of the organism beyond what is normal. Ethical controversy surrounds possible use of the both of these technologies in plants, nonhuman animals, and humans. WebAs opposed to gene-level mutations, mutations that alter longer stretches of DNA (ranging from multiple genes up to entire chromosomes) are called chromosomal mutations. These mutations often...
