i le fuaitau o loo i lalo ma tali le fesili mulimuli ane i le gagana lava lea e tasi e pei o le fuaitau: Faʻamatalaga: Nucleases o enzymes e tipiina DNA strands e catalyzing le hydrolysis o le phosphodiester sootaga. Nucleases e hydrolyse nucleotides mai le tuluiga o DNA strands ua taʻua o exonucleases, ao vavae endonucleases i totonu o strands. O le nucleases sili ona masani ona faaaogaina i molecular biology o le faatapulaaina endonucleases, lea vavae DNA i faasologa patino. Mo se faataitaiga, o le enzyme EcoRV faaalia i le itu tauagavale iloa le 6-faavae faasologa 5′-GATC-3′ ma faia se tipi i le laina faalava. I le natura, o nei enzymes puipuia siama mai phage siama e digesting le DNA phage pe a ulufale atu i le sela siama, o se vaega o le faatapulaaina faiga. I faatulagaga tekonolosi, o nei nucleases-faapitoa o loo faaaogaina i DNA molecular cloning ma cloning tamatamailima Fesili
Faʻasologa 6-base 5′-GATATC-3
