“Human Genetic Modification” means changing genes in a living human cell. There are two types of genetic modification.
Somatic modification involves adding genes to cells other than egg or sperm cells. Usuallly this type of gene modification is used against diseases. The modified genes wouldn’t be inherited to the following generations.
Germline modifications would change genes in eggs, sperms and early embryos. The modified genes would be inherited to the following generations.
Genes are found in the chromosomes which are located in the nuclei of the cells of the body. Genetic modification occurs by inserting genes into living cells. The desired gene is attached to a viral vector which can carry the gene across the cell membrane.
