SNP (Single Nucleotide Polymorphism)

Single Nucleotide Polymorphism, or SNP, refers to a variation in a single DNA building block, known as a nucleotide. In our genetic code, these small differences can occur among people, where one person might have the nucleotide "A" at a particular position in their DNA, while another person might have "G." SNPs can influence how individuals respond to diseases, medications, and environmental factors. They are essential in genetic research, helping scientists understand genetic diversity, disease susceptibility, and personalizing medicine to better fit an individual’s genetic makeup.
