Really need the passage for this since this organism is so unusual, if you don't remember this.
1. An extra S phase occurs during amitotic division in a small macronucleus to minimize fluctuations in DNA content. This is most likely trigerred by the presence of:
A. low concentratiosn of DNA in the macronucleus
C. High concentrations of DNA in the micronucleus
D. Mitotic enzymes in the micronucleus
answer is A.
