There once was a DNA that felt lonely, so he wanted to replicate itself, so he called the replication company for help. The replication company sent out helicase, who's job is to help unwind the DNA, which is a really simple task, because of the weak hydrogen bonds, this results in two strands (the initiation point where the splitting starts is known as the replication fork). Helicase's assistant, single-strand-binding protein has a very important job, they are to help stabilize the newly unwound single strands. The process was too painful for the DNA, but fortunately helicase had brought in his other co-worker Gyrase to ease his pain.
Act 2: Elongation
Now DNA is split into two strands, each running anti-parallel to each other. One strand is oriented in the 5' to 3' direction, while the other strand is oriented in the 3' to 5' strand. DNA polymerase attaches new nucleotides to the 3' end of the 5' to 3' strand (leading strand). Okazaki Fragments generate during the synthesis of the lagging strand of the 3' to 5' strand.
Act 3: Termination
Later, the Okazaki Fragments are joined together by DNA ligase, and POL 1 comes along to do a quality check of what happened (proofreading).
