Solution

The correct option is A Nucleotide precursors

A common laboratory technique used to make many copies (millions or billions) of a particular region of DNA is called Polymerase Chain Reaction(PCR). It requires a primer, DNA helicases, DNA polymerases, etc.,
So, the correct option is ‘ Nucleotide precursors’.
