Where is the PCR gene amplification scheme?

Gene amplifier is a programmable temperature cycler, which can change the temperature quickly and control the temperature accurately. The instrument is mainly used for gene separation, cloning and nucleic acid sequence analysis. Because of its high sensitivity, simple operation and time saving, it is the first choice for gene amplification analysis in life science research, biochemical analysis, clinical diagnosis, drug analysis, forensic identification, rapid inspection of epidemic situation and other fields. ?

The scheme block diagram is shown in the following figure:?
