The term restriction

Detailed explanation-1: -EcoRI is a restriction enzyme that derives its name from the bacterium Escherichia coli. R is for the strain RY13 and I (one) as it was the first enzyme to be isolated from the given strain. So EcoRI is pronounced as Eco-R-One.
Detailed explanation-2: -EcoRI comes from Escherichia coli RYB strain. In EcoRI, ‘E’ comes from the genus ‘Escherichia’and ‘co’ comes from the species ‘coli’. The letter ‘R’ is derived from the name of the strain RYB.
Detailed explanation-3: -In EcoRI, Eco represents the species of bacteria from which it is isolated i.e. Escherichia coli. R represents the strain of the bacteria which is RY-13 in this case.
Detailed explanation-4: -So, EcoRI was the first enzyme to be isolated from the RY13 strain of E. coli.
