Makovka662 [10]

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.
