The behavior of a single celled creature like Amoeba or Paramecium or
whatever is usually controlled by cytoplasmic factors like nutrient
concentration and levels of specific signaling molecules. Looking
into the structure of the nucleus won't help.
There are many aspects of protistan behavior that are completely
explainable on the molecular level. For example Google on "Paramecium
avoidance behavior" or, on a very technical level, read the De Ondarza
et al. paper on G proteins and Ca++ influx at
