Web13 mrt. 2024 · Restriction enzymes are called endonucleases because they cut double-stranded DNA, which is how DNA normally exists, at locations that are in between the ends of the DNA. There are more than 90 different restriction enzymes. Each recognizes a distinct restriction site. WebA major protective mechanism involves the use of restriction enzymes to degrade the invading viral DNA by cleaving it at specific restriction sites. At the same time, the host cell protects its own DNA from being cleaved by employing other enzymes called methylases, which methylate adenine or cytosine bases within host recognition sequences.
