Flap endonucleases (FENs, also known as 5' durgs in older references) are a class of nucleolytic enzymes that act as both 5'-3' exonucleases and structure-specific endonucleases on specialised DNA structures that occur during the biological processes of DNA replication, DNA repair, and DNA recombination. Flap endonucleases have been identified in eukaryotes, prokaryotes, archaea, and some viruses. Organisms can have more than one FEN homologue; this redundancy may gi… WebPublisher Summary This chapter describes the mammalian nucleolytic enzymes and their localization. A multitude of the enzymes of varying degrees of specificity exhibits …

Also, single DNA strands are more prone to damage by chemicals or nucleolytic enzymes. So, all known cells build specific proteins that bind to DNA single strands and protect them. greek restaurant south beach
