What would most likely happen to a cell undergoing mitosis if you introduced an inhibitor to Aurora B at prometaphase

The most likely outcome of the addition of an inhibitor to Aurora B in prometaphase of a cell undergoing mitosis is the fact that sister chromatid arms would not separate (Option B).

In conclusion, the most likely outcome of the addition of an inhibitor to Aurora B in prometaphase of a cell undergoing mitosis is the fact that sister chromatid arms would not separate (Option B).

Nuclear division will not occur in that cell

Please find the explanation below

Explanation:

Mitosis is a type of cell division in which two genetically identical daughter cells form from a single cell. The mitotic process occurs in stages, which includes the PROMETAPHASE described in this question. Prometaphase is the second stage of mitosis i.e after prophase and before metaphase.

Prometaphase stage is characterized by the degradation of the nuclear envelope in order to allow the sister chromatids to be separated into opposite poles. Also, a protein called KINETOCHORE forms at the centromere in order for the microtubules to attach to them in subsequent stages.

If an inhibitor is introduced into the cell at PROMETAPHASE stage, the activities described above, which are important for the separation of the chromatids, will not occur. Hence, the likely effect on the cells is INABILITY of NUCLEAR DIVISION TO OCCUR.

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
