Answer:
Addition of enzymes will increase the speed rate of DNA replication.
Helicase:
It is responsible for DNA strands unwinding and unzip the DNA strands from their center.
Primase:
It is responsible for 5' to 3' direction RNA primers synthesis, okazaki fragment's template.
Polymerase 3:
It synthesize the nucleotides from the 5' to 3' direction on leading end.
Polymerase 1:
It synthesize the nucleotide (okazaki fragments) on lagging strand.
Ligase:
It connects all okazaki fragments.
Topoisomerase:
Topoisomerases are used to regulate the super coiling.
