Single Nucleotide Polymorphisms (SNPs)

Single Nucleotide Polymorphisms (SNPs) are tiny variations in our DNA that involve a change in a single building block, called a nucleotide. Each nucleotide is one of four letters (A, T, C, G) that make up our genetic code. SNPs can occur throughout the genome and contribute to differences among individuals, such as eye color or susceptibility to certain diseases. They serve as important markers in genetics, helping researchers understand human diversity and the genetic basis of health and disease. Overall, SNPs play a crucial role in the study of genetics and personalized medicine.

    Single nucleotide polymorphisms (SNPs) are tiny variations in our DNA that occur when a single building block, or nucleotide, in the genetic code is different between individuals. For example, where most people may have an "A," some might have a "G." These small changes can influence everything from physical traits, like eye color, to susceptibility to certain diseases. SNPs are common in human genomes and help scientists understand genetic diversity, population evolution, and the relationship between genetics and health. They serve as important markers in genetic research and personalized medicine.
