What is the role of the primers in PCR?

Answer 1

DNA polymerase will now add the nucleotides in continuation to primer. DNA polymerase cannot simply add the nucleotides based on complementarity; instead, it requires the assistance of RNA primer. RNA primer is a short oligonucleotide strand that is complementary to our gene of interest, so it will form pairing with it.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
