DNA needs replication, because every cell produced by division of a pre-existing cell must be provided with an identical genetic material. However, Notes # Meaning of DNA Replication: A double-stranded DNA molecule is capable of producing two identical molecules from nucleotide monomers with the help of some proteins. o What enzymes make new DNA? DNA Replication - Basic lecture notes. Single-strand binding proteins stabilize the separated parental DNA strands and keep them from re-pairing.
