Question

What was the first type 2 restriction endonuclease discovered?

Answer 1

Restriction endonuclease:

1. Restriction endonuclease acts as molecular scissors, severing the DNA into distinct replicated pieces.
2. They cut DNA at certain locations and are one of the most significant classes of enzymes for DNA modification.
3. These are prevalent in bacterial cells and work as part of a protective mechanism known as the restriction-modification system.
4. Hind II was the first restriction endonuclease to be discovered.
5. This enzyme was initially identified from the Rd strain of Haemophilus influenza.
