Can you please help me with the following; thanks! An experiment that shows that there is a targeting system for a nuclear encoded protein that ultimately finds its way to a specific organelle.

Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below. Dilated cardiomyopathy (DCM) is a condition in which the wall of the heart, starting with the left ventricle, stretches and thins.  This prevents the heart from pumping effectively and can be life threatening.  The above graph shows mRNA expression (left pane) and protein expression (right pane) for three molecular components of cardiomyocytes (GJA3 is the gene that encodes for Connexin 46, DSP is the gene that encodes for Desmoplakin, and CTNNA3 is the gene that encodes for Catenin α-3) between DCM cells and healthy cardiomyocytes (CNT). Based on the above figure, which of the following issues are hearts with dilated cardiomyopathy likely to suffer? Options: impaired electrical conduction between cells impaired cell-cell communication poor cell-cell adhesion decreased energetic output from mitochondria impaired ability to pass mitochondria between cells
