B)DNA helicase.
C)a DNA template.
D)a thermocycler machine.
E)plasmid DNA.

Question

Quizplus · Accepted Answer

DNA polymerase is essential in both processes for synthesizing new DNA strands, and a DNA template is required to guide the synthesis of new DNA strands. DNA helicase is used in DNA replication in cells to unwind the DNA double helix but is not a component added in PCR, where high temperatures are used to denature the DNA. A thermocycler is specific to PCR for cycling temperatures, and plasmid DNA is not a requirement for either process to occur.
