According to the People's Daily reported on October 26th, 20165438/kloc-0, the team of He Jiankui in south university of science and technology of china, China suddenly announced that a pair of genetically edited babies named Lulu and Nana were born healthy in China, 5438+0 1. The news shocked the global academic community. One of the genes in the twins has been modified to make them naturally resistant to AIDS after birth. This is the first genetically edited baby immune to AIDS in the world, which also means that China has made a historic breakthrough in the application of gene editing technology in disease prevention.

We can't do experiments on children without permission! We can't change the child's body without authorization-even if it's just genes! But think about it, whose permission is the so-called "permission"? If this is the child's own permission-do we want the embryo to nod or shake its head? If parents allow them, do they have the right to change their children and control their own destiny? For a long time, even without this technology, some people kept saying "respect children's nature", in fact, they spared no effort to "transform children". The method used is called education.

The human body is composed of100000000000000000 cells, each cell is composed of 46 chromosomes, which is usually regarded as a genome. Among them, 23 were inherited by the mother and the remaining 23 were inherited by the father. For example, chromosomes are containers of genetic material, and a genetic gene consists of thousands of bases. Three bases represent the synthesis of an amino acid. According to the type and order of the base, each child's personality, appearance and illness will change.

So "genetic engineering" is to find out the 3 billion bases that make up the human body. If we find the base arrangement of chromosomes, we can prevent and treat all diseases and predict the occurrence of diseases in advance. Chromosomes have a profound influence on the reproductive process.
