How does one discern "non-coding" SNPs Bt comparing two or more sets of DNA & looking for variations whixh involve single bases. Don't ask me to explain the techniques used. <g> SNP Single nucleotide polymorphism: SNPs involve the change of one DNA base to another. SNPs and point mutations are structurally identical, differing only in their frequency. Variations that occur in 1% or less of a population are considered point mutations, and those occurring in more than 1% are SNPs. SNPs can occur in coding regions of the genome (cSNPs), in regulatory regions (rSNPs), or, most commonly, in "junk DNA" regions, in which case they are referred to as anonymous SNPs. genomicglossaries.com - You'll find a lot of information here (together with useful links)... nig
