Question

What is a type 2 restriction enzyme?

Answer 1

Type 2 restriction enzyme:

1. Proteins are called restriction enzymes to regulate the size of DNA molecules.
2. They accomplish this by cleaving repetitive DNA sequences or foreign DNA. Structure and recognition specificity is used to categorize restriction enzymes.
3. Type I, Type II, and Type III restriction enzymes are the three different subtypes.
4. Four DNA strands, two on each side of the DNA, make up type II restriction enzymes.
5. Typically, they break DNA when they detect two bases on one strand.
