Answer:
The DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape of red blood cells.
Explanation:
Sickle cell anemia is one of a group of disorders known as sickle cell disease. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body.
Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons. These rigid, sticky cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.
Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin). In sickle cell anemia, the abnormal hemoglobin causes red blood cells to become rigid, sticky and misshapen.
The sickle cell mutation reflects a single change in the amino acid building blocks of the oxygen-transport protein, hemoglobin. This protein, which is the component that gives red cells their color, has two subunits. The alpha subunit is normal in people with sickle cell disease. The beta subunit has the amino acid valine at position 6 instead of the glutamic acid that is normally present. The alteration is the basis of all the problems that occur in people with sickle cell disease.
DNA Polymerases type of enzyme ensures that the correct base for growing the chain is aligned with the template chain.
<h3>What is DNA Polymerase?</h3>
- The family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the basic building blocks of DNA, includes DNA polymerase.
- These enzymes, which are required for DNA replication, typically function in groups to divide an initial DNA duplex into two identical copies.
- DNA polymerase "reads" the pre existing DNA strands throughout this process to produce two new strands that are identical to the preexisting ones.
- Deoxyribonucleotides, the components of DNA, are synthesized by DNA polymerase as its primary purpose.
- The nucleotides and bases found on each strand of the original DNA molecule are paired to form the DNA copies.
- This coupling always occurs in certain pairings, with cytosine and guanine constituting one pair and thymine and adenine forming the other.
- RNA polymerases, on the other hand, create RNA from ribonucleotides that are either found in RNA or DNA.

The correct answer would be the second option. The abnormal development or growth of the cells that make up the inner lining of the cervix is known as cervical dysplasia. It is a pre-cancerous condition that involves an abnormal growth of cells in the lining of the endocervical canal which is the opening between the vagina and the uterus. A very common cause of developing this is the virus HPV or the human papillomavirus. It can be transmitted sexually and has many strains. This condition can still be cured when it is detected early. Without treating it, cervical dysplasia would develop to cancer.<span />
