Restriction enzyme names come from the organism they are isolated from. In Sam I, “S” stands for the genus Serratia and “am” comes from the species marcescens. Therefore, the enzyme Sam I is from Serratia marcescens, so the correct answer is B.

False!So, the restriction enzyme SmaI, which stands for Serratia marcescens enzyme, is derived from the bacterium Serratia marcescens. This enzyme is commonly used in molecular biology research to cut DNA at specific recognition sites. It recognizes the sequence 5'-CCCGGG-3' and cuts between the second and third C residues. This process is important for DNA manipulation and analysis in various experiments.
