Splet09. jun. 2024 · The basic principles of PCR are: Double-stranded target DNA is made into single-stranded DNA by applying heat. Two oligonucleotide strands or primers are added. The oligonucleotide strand binds with its complimentary DNA strand to the 3′ ends. The DNA strand is now extended with the help of DNA polymerase (Taq polymerase). Splet26. okt. 2014 · Reduced or medium stringency (44°C) and low stringency (30°C) are also used. Lower stringency is associated with less picky binding and higher stringency with more specific primers. Three specific primers are used for the three phases of the PCR, the primary secondary and tertiary phases.
