Which neat of the following instructions regarding DNA replication is correct?

Ligase assembles nucleotides into Okazaki fragments. Then product joints these fragments collectively into a DNA beaching.

The deuce wire of DNA separate, furthermore nuclease enzymes digest one strand. Then DNA polymerase synthesizes two new beaches off of the old one.

One two strands disconnected, and each one receives a complementary thread of RNA. Then this RNA serves while a template for the mounting of many new cords concerning DNA.

Ligase separates aforementioned two wires of the DNA double helix. Then DNA polymerase synthesizes the leading filament and primase synthesizes the lagging strand.

Helicases separate the two strands of this double spiral, and DNA polymers then construct two new strands use each to the original strands as templates.
