SOLVED:(A) Real-time polymerase chain reaction (qPCR). Real-time polymerase chain reaction, also called quantitative polymerase chain reaction (qPCR), is a laboratory technique for exponential amplification and quantification of short DNA sequences. A qPCR experiment was undertaken to compare the gene expression levels from two different plant lines ("wild type" and "runt"). The fluorescence level is registered at 45 cycles and normalized so the maximum is 100 %. The researchers wish to use the
