Answer:
DNA template can be correctly matched with B.
Primers can be correctly matched with D.
The master mix can be correctly matched with E.
dNTPs can be correctly matched with A.
The original DNA, which one desires to copy using PCR is termed as the DNA template. Primers refer to the small segments of DNA, which match terminals of the template so that it can be duplicated.
Mastermix refers to the solution, which comprises all the constituents including the nucleic acids, enzymes, and the ions to construct novel DNA. The solitary nucleic acids that act as building blocks when new strands of DNA are constructed are called dNTPs.
