What Is a Standard Drink? A standard drink is any drink that contains about 14 grams of pure alcohol (about 0.6 fluid ounces or 1.2 tablespoons). Below are standard drink equivalents as well as the number of standard drinks in different container sizes for each beverage.
A single-nucleotide polymorphism, often abbreviated to SNP (/ËsnÉªp/; plural /ËsnÉªps/), is a variation in a single nucleotide that occurs at a specific position in the genome, where each variation is present to some appreciable degree within a population (e.g. > 1%).
SNPs (Single Nucleotide Polymorphisms) are common DNA variations where a single base-pair has been mutated or deleted. They occur every 300-2k bp on average, and are ~20E6 SNPs within a genome that is ~3E9. SNPs are believed to come from point-mutations that occur throughout evolution as a normal process of variation.
