British scientists have filed a request to the Government for genetic modification of human embryos. This happened just a few months after the scientific world learned of similar experiments in China, caused a storm of protests. Experiments are going to spend in Francis Crick Institute in London. They last about two weeks and the embryos cannot be brought to the condition of the fetus. Egg and sperm to donate a pair of experiments in which a surplus after they have undergone in vitriol fertilization.
The ultimate goal of researchers – to solve the problem of miscarriages. By modifying human embryos, they want to identify the genes most active force in the early days of fetal life, when the embryo forms a cell – the foundation of the future placenta.Genes are switched on and off using a tool Crispr-Cas9.The knowledge Read the rest of this entry »
