Answer:
The lack of Mad1 protein can cause faster cell division.
Explanation:
The Mad1 protein is responsible for regulating the fixation of chromosomes in spindle microtubules, during cell division. With the presence of this protein, anaphase is prevented from starting while the spindle, where the chromosomes attach, is formed.
Without this protein, this check is not done and cell division occurs faster, which is one of the reasons why cell division can be accelerated.
The answer would be: regression
Regression is a defense mechanism that causes the person fall into earlier psychological stages when an unpleasant stimulus received. The person chooses to turn back rather than facing the problem, which was seems safer and easier.
In this case, the 6-years old child starts to wet his bed, a sign that should be found in the baby(earlier stage).
