For example, the purification of proteins and specific nucleic acids often requires the digestion of DNA, RNA or both. In living organisms, they are essential machinery for many aspects of DNA repair. coli strain containing a genetic fusion of the micrococcal nuclease gene (Gene ID: 3238436) and the gene coding for maltose binding protein, or MBP. The restriction endonuclease Fok1, naturally found in Flavobacterium okeanokoites, is a bacterial type IIS restriction endonuclease consisting of an N-terminal DNA-binding domain and a non sequence-specific DNA cleavage domain at the C-terminal. CRISPR-CAS9 DALAM REKAYASA KROMOSOM. In living organisms, they are essential machinery for many aspects of DNA repair.
