  • DNA replication begins at a site called the origin of replication.
    DNA replication begins at the origin of replication.
  • Why is DNA replication important?
    DNA replication is important for ensuring genetic continuity during cell division.
  • What are two enzymes used in DNA replication?
    DNA helicase and DNA polymerase are two enzymes used in DNA replication.
  • The three steps required for DNA replication are unwinding, synthesis, and joining fragments.
    The three steps are unwinding the DNA, synthesizing new strands, and joining Okazaki fragments.
