a SNP can be used as a DNA marker
1 answer
Yes, a single nucleotide polymorphism (SNP) can be used as a DNA marker. SNPs are variations in a single DNA base, and they occur naturally throughout the human genome. When comparing the genomes of different individuals or populations, scientists can use SNPs as genetic markers to track the inheritance of traits, identify disease-causing mutations, or determine genetic relatedness. SNPs are highly stable and easy to analyze using PCR-based techniques, making them useful tools for genetic research and clinical diagnostics.
