What are DNA primers?

Explanation:
DNA primers are short single-stranded DNA sequences that bind to a specific region of the DNA by complementary base pairing. They provide a starting point with a 3' end for DNA polymerase to begin adding nucleotides, which is essential for copying or amplifying a target sequence. In PCR, two primers flank the region to be amplified, one binding to each strand and guiding the enzyme to extend in the correct direction. They’re not enzymes, and they’re not long double-stranded fragments; their single-stranded nature lets them hybridize precisely to the template and kick off synthesis.
