Types of SNPs. Single nucleotides may be changed (substitution), removed (deletions) or added (insertion) to a polynucleotide sequence. Single nucleotide polymorphisms may fall within coding sequences of genes, non-coding regions of genes, or in the intergenic regions between genes.
Whole Foods charges $2.99 and Sprouts has the same price, so far so good. Now for one of my favorite snacks cheese curls, yummy! Sprouts sells a 6-ounce bag for $1.99 which comes to $.31 per ounce. Whole Foods is same price, $1.99, but their bag is 7 ounces so that means their cheese curls cost less at $.28 per ounce.
