<h3>Describe Eco-RI.</h3>
The bacterium Escherichia coli contains the globular type II restriction enzyme known as Eco-RI endonuclease (Eco-RI). Like many other endonucleases found in bacteria and archaea, this one serves as a defense mechanism to keep the cell from being overrun by foreign DNA.
<h3>Describe EcoRV-HF.</h3>
EcoRV-HF was designed for lower star activity, although it has the same specificity as EcoRV . Cleaves in the tetracycline resistance gene of pBR322 to leave a ligatable blunt end. some combinations of overlapping CpG methylation are impaired.
