Parkinson's disease
<h3>What is Parkinson's disease?</h3>
Parkinson's disease (PD) is a neurodegenerative ailment that primarily affects dopamine-producing ("dopaminergic") neurons in the substantia nigra, a particular region of the brain.
In most cases, symptoms appear slowly over many years. Due to the variety of the condition, the evolution of symptoms can vary a little from person to person. People with PD might go through:
- Tremor in the hands that is typically described as pill-rolling tremor when at rest. There may be additional tremor types.
- Bradykinesia
- Limb stiffness
- Balance and gait issues

Answer:
The inactivation of one protein that slow down the cell cycle could lead to cancer. (option b).
Explanation:
The cell cycle is the process a cell undergoes when it divides during its life. This process includes a control mechanism to prevent normal cells from replicating more than normal, called cell cycle regulation.
In oncogenesis - the formation of malignant tumours - many factors induce the abnormal growth of a tissue by the abnormal multiplication of the cells that form it, leading to cancer. One of these factors may be a mutation in the DNA that prevents the production of regulatory proteins.
The mutation that produces exaggerated cell growth -and which can eventually lead to cancer- can create defects in a specific regulatory protein that slow down the cell cycle, so that exaggerated and uncontrolled cell replication occurs.
Once a tumor tissue has formed, successive mutations will lead to a lack of cell differentiation, the property of forming blood vessels, the ability to invade tissue and lose its apoptosis mechanism, that characterizes cancer cells.
