what is a genomic snp
Single nucleotide polymorphism analysis and mutation detection. SNP DEFINITION. DNA sequence variations that occur when a single nucleotide (A, T, C, or G) in the genome sequence is altered.Each individual has many single nucleotide polymorphisms that together create a unique DNA pattern for that person.SNPs promise to significantly advance our ability to understand and treat human disease.NA sequence variations that occur when a single nucleotide (A, T, C, or G) in the genome sequence is altered. Each individual has many single nucleotide polymorphisms that together create a unique DNA pattern for that person.
