sentences:  This mechanism is conserved from prokaryotes to eukaryotes and is known as semiconservative DNA replication.The process of semiconservative replication for the site of DNA replication is a fork-like DNA structure, the replication fork, where the DNA helix is open, or unwound, exposing unpaired DNA nucleotides for recognition and base pairing for the incorporation
  of free nucleotides into double-stranded DNA.Initiation of eukaryotic DNA replication is the first stage of DNA synthesis where the DNA double helix is unwound and an initial priming event by DNA polymerase α occurs on the leading strand.
