Answer:

Parkinson's disease

Explanation:

Parkinson's is a progressive degenerative disorder in which neurons are affected in basal ganglia and substantia nigra of brain. These neurons are responsible for producing dopamine transmitter and in Parkinson's they start to die.

Loss of around 80% of dopamine results in the symptoms like Bradykinesia (slow movement, decreased blinking, drooling), stiffness, tremor, balance problem etc. Treatment is done by medication, brain stimulation surgery, exercise and diet.

chubhunter [2.5K]

Answer:

The correct answer is C. be more likely to have cancer at some point in his/her life.

Explanation:

Cell cycle checkpoints are controlled by different proteins which are coded by different genes. They are important in cell cycle regulation and stops cell cycle immediately if they find any problem in the cell like mutation.

The cell cycle will not be continued if the problem does not solve and cell death will occur which prevents cancer by preventing the mutation to spread into new cells.  

Therefore if a mutation occurs in certain genes that enforce a checkpoint on the cell cycle then the mutated gene will pass in new cells and the mutated cells will grow uncontrollably due to no checkpoints so the person will probably have cancer at some point in his or her life.
