Replication inserts the normal (nonmodified) bases into the daughter strands. This generates hemimethylated DNA, in which one strand is methylated and one strand is unmethylated.

Third heart sound (S3) 

normal in children but is not heard in normal adults

indicates volume overload, as in congestive heart failure or advanced mitral or tricuspid regurgitation.

The function of the ventricles is described by the following three parameters: 

Stroke volume 

Ejection fraction 

Cardiac output
