Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Nucleases sune enzymes waɗanda ke yanke igiyoyin DNA ta hanyar haɓaka hydrolysis na haɗin phosphodiester. Ana kiran nucleases da ke hydrolyse nucleotides daga ƙarshen igiyoyin DNA exonucleases, yayin da endonucleases ke yankewa a cikin igiyoyi.
