The naming convention of the restriction enzyme EcoRI comes from
A{'text': 'The chemical composition of the enzyme', 'label': 'A'}
B{'text': 'The country of discovery', 'label': 'B'}
C{'text': 'Genus + species + strain + order of discovery', 'label': 'C'}
D{'text': 'The bacterial phenotype', 'label': 'D'}
Answer & Solution
Correct answer: C. {'text': 'Genus + species + strain + order of discovery', 'label': 'C'}
1. Restriction enzymes are named systematically.
2. The first letter comes from the genus (Escherichia → E).
3. The next two come from the species (coli → co).
4. The letter after that comes from the strain (R for RY13); Roman numerals give the discovery order (I means first).
