Options
- AHin d II
- BProtease
- CDNase I
- DRNase
Correct answer
A. Hin d II
Step-by-step solution
Hin d II is a type of restriction endonuclease. A restriction enzyme or restriction endonuclease is an enzyme that cleaves DNA into fragments at or near specific recognition sites within the molecule known as restriction sites. Restrictions enzymes are one class of the broader endonuclease group of enzymes. Restriction enzymes are commonly classified into five types, which differ in their structure and whether they cut their DNA substrate at their recognition site, or if the recognition and cleavage sites are separ
