SpletPCR primers are synthetic DNA oligonucleotides of approximately 15–30 bases. PCR primers are designed to bind (via sequence complementarity) to sequences that flank the region of interest in the template DNA. During PCR, DNA polymerase extends the primers from their 3′ ends. SpletPCR Answers Previous Level 1. Each round of replication leads to a doubling of the amount of DNA in the region between the primers. However, the final PCR product does not appear until the third round of …
