PCR Diagram Generator

A PCR diagram shows one target sequence being copied through thermal cycling. It draws the double-stranded template separating, primers binding to each strand, and polymerase extending new strands, then repeats to show the copy number doubling each cycle. A pcr reaction diagram usually labels the temperature at every stage.

Denaturation, annealing, and extension, repeated each cycle. Denaturation melts the double helix into single strands, annealing lets short primers bind to the flanking sequences, and extension lets a heat-stable polymerase synthesise the complementary strand. A pcr steps diagram places these three in a repeating loop rather than a straight line.

Roughly 95°C, 50-65°C, and 72°C for the three steps. Denaturation runs near 95°C, annealing sits between 50°C and 65°C depending on primer melting temperature, and extension runs at 72°C where Taq polymerase is most active. Labeling these on a pcr cycle diagram is what makes it useful as a protocol figure.

Describe the stages, temperatures, and labels you need. SciFig's pcr diagram generator lays out the cycle with the template, primers, polymerase, and temperature annotations in place, at publication resolution — so the figure can go directly into a methods section or a protocol appendix.

Template DNA, two primers, dNTPs, a heat-stable polymerase, and buffer with magnesium. The forward and reverse primers define the amplified region, dNTPs supply the building blocks, and Taq polymerase survives repeated heating. SciFig's pcr diagram generator can show these reagents as a labeled tube alongside the cycle itself.

RT-PCR starts from RNA instead of DNA. A reverse transcriptase step first converts RNA into complementary DNA, and only then does standard thermal cycling begin, which is why an RT-PCR figure has an extra stage before the loop. Quantitative PCR is a separate distinction — it measures product as it accumulates.
