A layman’s talk about genetic diversity

A gene is a specific sequence of bases on DNA. Since DNA is composed of four bases: G, A, T, and C, and the arrangement of these four bases can be ever-changing, the number of bases is the length of the gene. They are also different, resulting in genetic diversity. The friend above is not completely correct. Gene diversity has nothing to do with base pairing, because G matches C, and A matches T. This is certain, and there is no room for change. Unless there are errors when your genes are copied, that is a genetic disease. . It doesn’t matter what the folding method and spatial structure are, because the folding method and spatial structure of DNA are also fixed, and the diversity of proteins is related to the spatial structure.
