While the overall structure of human DNA is remarkably similar among individuals, there is also significant genetic variation. This variation arises from differences in the sequence of nucleotides within the genome. Variations can occur through mutations, which are changes in the DNA sequence that can be inherited or arise spontaneously. Genetic variation is the basis for diversity among individuals, influencing traits such as appearance, susceptibility to diseases, and responses to medications and environmental factors. Studying these variations is crucial in understanding human evolution, genetic diseases, and personalized medicine.
