Question

Which of the following is not a restriction endonuclease?

• A. Eco RI
• B. Hind III
• C. Pst I
• D. DNAse I

Answer 1

The correct option is D DNAse I

Restriction endonucleases are the enzymes, which cut a DNA molecule within certain specific sites that have a specific base sequence, e.g. Hae III, Eco RI, Bam II, Hind II, Pst I, etc.
DNase-I is a versatile enzyme that nonspecifically cleaves DNA to release 5'-phosphorylated di-, tri-, and oligonucleotide products
