Scientists in London have been granted permission to edit the genomes of human embryos for research, UK fertility regulators announced. The 1 February approval by the UK Human Fertilisation and Embryology Authority (HFEA) represents the world’s first endorsement of such research by a national regulatory authority.
Genome editing, or genome editing with engineered nucleases (GEEN) is a type of genetic engineering in which DNA is inserted, deleted or replaced in the genome of an organism using engineered nucleases, or “molecular scissors.
A genome is an organism’s complete set of DNA, including all of its genes. Each genomecontains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus.
A Genes, which is made up of DNA, is the basic physical and functional unit of heredity and act as instructions to make molecules called proteins.
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria. Watson and Crick discover chemical structure of DNA
Embryos organism in the earliest stage of development. In humans this is defined as the developing organism from the fourthday after fertilization to the end of the eighth week. After that the unborn baby is usually referred to as the fetus.
