Another cycle and you would have four another, you would have … SpletThe most important enzyme in a PCR reaction is called taq polymerase. A polymerase is an enzyme that attaches molecules together, and we just so happen to want to attach many nucleotides (the building blocks of DNA) together, so it works out for us. Every cell that has DNA has its own polymerase that takes care of replication of DNA.

SpletHow many cycles of PCR to produce this many from a single template molecule? 2 n = 1.5x 10 12. nlog2 = log(1.5) + log(10 12) nlog2 = 12.18. n = 12.18/ log2 = 41 cycles. Of course this in an absolute upper limit. The estimate assumes that you start with one template molecule of 1 kb, and that dNTPs aren't being hydrolysed, or otherwise degraded.

SpletThat means for 94% efficiency on a 5-log range, the assay would have a range of 88% to 100% efficiency. To accurately determine the efficiency of a PCR reaction, a 5-log dilution series must be performed. A slope of –3.3 ±10% reflects an efficiency of 100% ±10%. A PCR reaction with lower efficiency will have lower sensitivity. R 2 value
