C. Clogged arteries
D. Skin cancer
D. Skin cancer
D. Skin cancer
A mutation that causes abnormal cell division can result in the development of skin cancer. Such mutations can disrupt the normal regulation of cell growth and division in skin cells, leading to the uncontrolled growth of abnormal cells in the skin.
To determine the correct answer to this question, we need to understand what each of the options refers to.
A. Cystic fibrosis: Cystic fibrosis is a genetic disorder that affects various organs in the body, particularly the lungs, pancreas, and liver. It is caused by a mutation in a specific gene called the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which leads to the production of abnormal proteins that disrupt the function of cells responsible for producing mucus, sweat, and digestive fluids. However, cystic fibrosis is primarily related to issues with ion transport rather than abnormal cell division. So, it is less likely to be the correct answer.
B. Sickle cell anemia: Sickle cell anemia is an inherited blood disorder characterized by abnormal red blood cells. It is caused by a mutation in the hemoglobin gene, which leads to the production of abnormal hemoglobin proteins that cause red blood cells to become rigid and sickle-shaped. Similar to cystic fibrosis, sickle cell anemia is primarily related to issues with protein structure rather than abnormal cell division.
C. Clogged arteries: Clogged arteries, also known as atherosclerosis, refer to the accumulation of fatty plaques within the arterial walls, leading to a narrowing of the blood vessels and reduced blood flow. While abnormal cell division could potentially contribute to the development of certain types of tumors in blood vessels (e.g., angiosarcoma), clogged arteries are typically not caused by abnormal cell division.
D. Skin cancer: Skin cancer is a type of cancer that originates in the cells of the skin. Different types of skin cancer exist, such as basal cell carcinoma, squamous cell carcinoma, and melanoma. These cancers can result from mutations that cause abnormal cell division in skin cells. Exposure to ultraviolet (UV) radiation from the sun or artificial sources is a major risk factor for skin cancer and can lead to mutations in the DNA of skin cells, resulting in uncontrolled cell growth and the formation of cancerous tumors. Therefore, the mutation that causes abnormal cell division is more likely to be associated with the development of skin cancer.
Based on this analysis, the correct answer is D. Skin cancer.
