👉 Variolization is a process in which a DNA molecule undergoes a series of chemical modifications that result in a change in its structure and function. This can occur due to various biological processes, such as mutation or genetic recombination, where the sequence of nucleotides within a DNA molecule is changed by random chance or through the action of external factors. Variolization can have several implications for the organism's ability to reproduce and survive. For example, it could lead to the loss of genetic diversity
