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.
DNA gyrase, or simply gyrase, is an enzyme within the class of topoisomerase (Type II topoisomerase) that relieves strain while double-stranded DNA is being unwound by helicase. The enzyme causes negative supercoiling of the DNA or relaxes positive supercoils. It does so by looping the template so as to form a crossing, then cutting one of the double helices and passing the other through it before releasing the break, changing the linking number by two in each enzymatic step.
