WebA Cas9 enzyme attaches to a particular DNA sequence when it is produced in a bacterial cell, and it subsequently cuts the DNA at that point. Compared to restriction enzymes, the Cas9 enzyme is far more effective in identifying and cleaving particular DNA sequences, and it can detect a much greater variety of sequences. WebGeneticists use restriction enzymes to isolate a segment of DNA that contains a gene of interest, for example, the gene that regulates the production of insulin. A plasmid is extracted from its bacteria cell and treated with the same restriction enzyme can hybridize with this fragment’s “sticky” ends of corresponding DNA.
WebRestriction Enzyme – generally added at 10% of the final volume 10X Buffer – a solution of salts which maintain the correct pH for the enzyme to function. “10X” refers to the fact that it is ten times more concentrated than it needs to be and so must be diluted by the addition of the other reagents.
