Genetic engineering has 3 factors it requires which are, the gene being transferred, a host cell into which the gene is inserted too and a biotic agent that separates
the reproductive structures. These 3 factors play a huge role in genetic engineering. The way in which the procedure is done is that the egg and sperm are combined to form an embryo the DNA of those cells or otherwise the embryo is then corrected to prevent genetic diseases which then will fixes passing those genetics on to the future generations.
Michael Selgelid for the Human Bioethics at Monash University said that disease’s that have a negative impact on someone's life might be able to become possible to delete the genetic order from their genomes and as well as if individuals are missing a genetic sequence needed for their health then it might also become possible to insert the sequence into their genomes. There are other diseases that are believed that could be prevented with genetic engineering, Lord Winston from The Human Body research in London said that changing the primary ‘blueprint of the father's sperm cells before fertilization could prevent cystic fibrosis in children. However Dr David King said that anything that altered human DNA is Dangerous.
