Questions

Nоrmаl develоpment оf the heаrt аtria requires left-right differentiation during embryonic development.  Microarray analysis identified 77 genes with preferential expression in one of the two atria, one of the genes identified was Pitx2c.  The differential expression of Pitx2c was confirmed by RT-qPCR.  The figure below represents the  amplification plot of one RT-qPCR run where e10 represents the amplification of Pitx2c in the left atrium, e9 represents the amplification of Pitx2c in the right atrium, and NTC represents the no template control (not relevant for this question).  Based only on the data shown, which of the following statements best describes the analysis of these data?
