Answer:
One of the structural barrier that a cell might have to overcome in order to go through mitosis is described below.
Explanation:
Structural barriers can be described as any of the structural changes in the structures of the body which do not allow it to perform its normal function.
The chromosomes of a cell have to arrange in a certain manner for the process of cell division to occur. Sometimes, the chromosomes might become so damaged that the normal DNA repair factory is unable to repair the chromosomes. The damage in the chromosomes might arise due to a number of reasons such as exposing to UV light or any kind of toxic chemical. To overcome this obstacle, certain extrinsic factors can be utilized to fix the damaged chromosomes. This is an example of the structural barriers which might be overcome by a cell for mitosis.
