Nowadays, newborns will adopt gene preservation. In the United States, the European Union, Australia and other developed countries, there are institutions that provide gene preservation services. Its patented technology has the characteristics of solid preservation at room temperature, which can realize family self-preservation.
Extended data:
It is true that the human body will have gene mutation or gene damage due to environmental influence, leading to diseases such as cancer. But these mutations only occur in some local cells of the body, and the gene sequence in other parts will theoretically remain the same as at birth. However, in real life, genes will be damaged or mutated more or less, and mutations at non-key sites in the genome only cause the accumulation of mutations and do not affect the normal growth of cells.
The mutation of key sites will affect the growth of cells, and the combination of a group of key sites will make cells cancerous, which is called accidental mutation. Therefore, without the original gene sequence of infancy as a reference, it is impossible to really say that the gene sequence of other parts without lesions must be exactly the same as that at birth.
