A mutation that causes abnormal cell division can result in skin cancer.
To determine which of the given options can be caused by a mutation that results in abnormal cell division, let's break down each option and consider the relationship between the mutation and the condition:
1. Cystic fibrosis: Cystic fibrosis is a genetic disorder caused by a mutation in the CFTR (cystic fibrosis transmembrane conductance regulator) gene. This mutation affects the production of a protein involved in regulating the flow of salt and fluids in the body, leading to the accumulation of thick, sticky mucus in various organs. However, it is not directly related to abnormal cell division; it is related to a specific gene mutation.
2. Clogged arteries: Clogged arteries, also known as atherosclerosis, is a condition where fat, cholesterol, and other substances build up in the artery walls, leading to narrowing and reducing blood flow. Abnormal cell division is not directly linked to clogged arteries. Rather, the development of this condition is influenced by factors like high cholesterol, smoking, high blood pressure, and certain lifestyle choices.
3. Skin cancer: Skin cancer is primarily caused by damage to the DNA in skin cells, usually due to exposure to ultraviolet (UV) radiation from the sun or tanning beds. This DNA damage can result in uncontrolled cell growth and division, leading to the formation of cancerous tumors. Mutations caused by abnormal cell division can potentially contribute to skin cancer development.
4. Sickle cell anemia: Sickle cell anemia is a genetic disorder caused by a mutation in the HBB (hemoglobin beta) gene, which affects the structure and function of red blood cells. This mutation leads to the production of abnormal hemoglobin, resulting in red blood cells that are shaped like sickles and prone to getting stuck in blood vessels. Similar to cystic fibrosis, sickle cell anemia is not directly caused by abnormal cell division but by a specific genetic mutation.
Based on the above explanations, the option that can be caused by a mutation resulting in abnormal cell division is skin cancer.
