Mutation in the CFTR gene >>>>>> Production of defective CFTR protein >>>>>> defective CFTR protein in cell membrane or no protein at all   >>>>>>>   Impaired ion transport across the cells   >>>>>>>   Cells secrete less chloride >>>>>>>   leads to more re-absorption of sodium and water into the cells   >>>>>>>   decreased hydration of mucus present outside the cells as more water is absorbed into the cells    >>>>>>>>   thick viscous mucus.

What is a structural barrier that a cell must overcome in order to go through mitosis?
Ierofanga [76]

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.
