Restriction endonucleases are enzymes witch catalyze the cleavage of nucleic acids at specific sequences. DNase act on DNA and RNase restrict RNA polymers. EcoR1 is a restriction enonuclease and a DNase, Which can recognise the palindromic sequence ‘GAATTC’. EcoR1 can be used to cleave, plasmid - pBR322 producing sticky ends. These can then accept transgenes with the same ‘sticky ends’, they are cemically bonded by enzyme ligase.

They’re useful in biotechnology. EcoR1 was isolated form E. coli. I love how creepy the video is LOL’d when I read the following comment: ’I clicked on this to learn, not to shit my pants. Holy shit.’!
