A mutation that causes abnormal cell division can result in skin cancer, cystic fibrosis, sickle cell anemia, and clogged arteries.
To determine which response is correct, we need to understand how mutations can result in abnormal cell division and subsequently lead to different conditions.
1. Skin Cancer: Mutations in certain genes can disrupt the regulation of cell division in skin cells, leading to uncontrolled growth and the formation of tumors. UV radiation from the sun is a common cause of these mutations.
2. Cystic Fibrosis: This is a genetic disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. These mutations affect the function of the CFTR protein, which is involved in the transport of chloride ions across cell membranes. As a result, the cells in various organs, particularly the lungs and pancreas, produce abnormally thick and sticky mucus.
3. Sickle Cell Anemia: This is an inherited blood disorder caused by a mutation in the hemoglobin gene. The mutation leads to the production of abnormal hemoglobin, which causes red blood cells to become misshapen (sickle-shaped) and prone to clumping together. These abnormal cells can get stuck in blood vessels, leading to reduced oxygen delivery and various complications.
4. Clogged Arteries: Mutations can contribute to the development of clogged arteries, also known as atherosclerosis. These mutations can affect genes involved in cholesterol metabolism and inflammation, leading to the accumulation of fatty deposits (plaques) on the inner walls of arteries. Over time, these plaques can restrict blood flow and potentially cause a heart attack or stroke.
Based on the information provided, it is clear that all four options can be caused by mutations that result in abnormal cell division. Therefore, all of the given responses (skin cancer, cystic fibrosis, sickle cell anemia, and clogged arteries) are correct.
