Which option gives a correct common feature of EcoRI and BamHI?

Answer and explanation

Correct answer: Both are restriction enzymes

EcoRI and BamHI are both restriction endonucleases used in molecular biology to cut double-stranded DNA at defined recognition sequences. Their exact recognition sequences and cleavage patterns are different, so they should not be treated as identical enzymes. Nevertheless, the common feature asked here is that both belong to the restriction-enzyme class and act as sequence-specific DNA-cutting tools. Therefore option A is correct. Options B, C and D refer to hormones, vitamins and lipids, which are different biological categories and do not describe either EcoRI or BamHI. The question asks for a shared classification, not for their individual recognition sequences.
