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%).
What are single nucleotide polymorphisms (SNPs)? Single nucleotide polymorphisms, frequently called SNPs (pronounced âsnipsâ), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block, called a nucleotide. For example, a SNP may replace the nucleotide cytosine (C) with the nucleotide thymine (T) in a certain stretch of DNA. SNPs occur normally throughout a personâs DNA. They occur once in every 300 nucleotides on average, which means there are roughly 10 million SNPs in the human genome.
