An example of the limitations of the replicator system is a line in 
ÒSins of the FatherÓ in which Picard claims to find replicated caviar inferior 
to the real thing. (On the other hand, we wonder if the good captain could 
really tell the difference in a blind taste test.) Another example of replicator 
limits is the single-bit DNA errors that led Data and Beverly to suspect 
Romulan trickery in the episode ÒDataÕs Day.Ó  Æ
