sickle cell anemia
A mutation that causes abnormal cell division can result in the following conditions:
1. Sickle cell anemia: This condition is caused by a mutation in the gene responsible for producing hemoglobin, a protein that carries oxygen in red blood cells. The abnormal cell division leads to the production of sickle-shaped red blood cells, which can cause various complications.
2. Clogged arteries: Abnormal cell division can contribute to the development of atherosclerosis, a condition characterized by the build-up of fatty deposits and inflammation in the arterial walls. This can eventually lead to the narrowing and blockage of arteries, restricting blood flow to vital organs.
3. Skin cancer: Mutations that affect cell division can disturb the normal growth and repair processes in the skin, leading to the development of cancer. Exposure to ultraviolet (UV) radiation, toxins, or certain genetic factors can increase the risk of these mutations occurring and resulting in skin cancer.
4. Cystic fibrosis: This genetic disorder is caused by mutations in the CFTR gene, which affects the production of a protein involved in the regulation of chloride ion channels. The abnormal cell division can lead to the production of thick, sticky mucus that affects various organs, particularly the lungs and digestive system.
To determine the correct answer, we need to understand the different mutations and their associated conditions.
A mutation is a change in the DNA sequence of a gene. Mutations can lead to various outcomes, including abnormal cell division and the development of certain health conditions.
Out of the options given, the mutation that causes abnormal cell division and leads to a specific health condition is cystic fibrosis.
Cystic fibrosis is a genetic disorder caused by a mutation in the CFTR gene. This mutation affects the production of a protein that regulates the movement of salt and water in and out of cells. As a result, the mucus in various organs, such as the lungs and digestive system, becomes thick and sticky, leading to difficulties in breathing and problems with digestion.
Sickle cell anemia is a genetic disorder caused by a mutation in the hemoglobin gene. It results in the formation of abnormal hemoglobin, leading to misshapen red blood cells, which can cause pain, anemia, and organ damage.
Clogged arteries are typically a consequence of the buildup of cholesterol and fatty substances in the arteries, known as atherosclerosis. It is not directly caused by a mutation.
Skin cancer can be caused by mutations resulting from exposure to ultraviolet (UV) radiation, but not specifically related to abnormal cell division.
So, the correct answer is cystic fibrosis, as a mutation in the CFTR gene causes abnormal cell division and leads to this condition.
