Question
Chapter 13.5, Problem 1HYEW
Summary Introduction
To explain:
Why bruises turn colors.
Introduction:
Bruises are a discoloration and tenderness of the skin caused by the leakage of the blood cells from a ruptured blood vessel into the tissues. A small bruise is called the ‘petechia’. When a bruise becomes a disease, it is called ‘purpura’.

One of your patients, a six-year-old girl who suffers from Sickle cell anemia, an inherited blood disorder in which red blood cells are abnormally shaped and fragile, leading to a short supply of red blood cells. These abnormal cells can also get stuck in small vessels, which prevent blood flow, leading to fatigue, pain, and other severe complications.
Patients with sickle cell anemia produce defective beta-globin due to a point mutation that causes the change of a single amino acid residue. This is an example of what type of mutation?
nonsense mutation
missense mutation
frameshift mutation
deletion mutation
Gene Expression and the Impact of a Mutation.
Can someone help me to answer the question 8 and 9, please?
8. How has the mutation altered the polypeptide? Is the function of the hemoglobin molecule (which includes 2 ẞ-globin polypeptides and 2 a-globin polypeptides) impaired? (Read your book to learn more about sickle cell disease.)
9. What is the relationship between the genotype in this case and the individual's phenotype?
asap please

- Sickle-cell disease (often called sickle-cell anemia) is a disease that is caused by a mutation to the gene that is responsible for producing the protein hemoglobin. Remember that hemoglobin is a protein in the red blood cells which is responsible for carrying oxygen throughout the body. When a person possesses the mutated hemoglobin allele, their red blood cells take on an altered shape and this results in a variety of symptoms ranging from general weakening of the body, damage to the organs and even death. The sickle cell allele is recessive to the healthy allele, thus only individuals that are homozygous for the recessive allele will have sickle-cell disease. Individuals that are homozygous for the healthy allele, along with heterozygous, individuals will be physically healthy. Question: Given that this mutated allele will cause disease and death in individuals, what would you predict to occur to the frequency of this allele in the population?

- Mutations in the RB gene are often associated with cancer. Explain how a mutation that results in a nonfunctional RB protein contributes to cancer.arrow_forwardHair color is due to the presence of melanin. There are two types of melanin produced by melanocytes. One is eumelanin, which is responsible for black (homozygous), brown (heterozygous), and blond (recessive) hair colors. The other is pheomelanin, which is responsible for red hair color. During melanin synthesis, MCR1gene converts pheomelanin to eumelanin. However, a variant of the MCR1 gene (MCR1variant), prevents this conversion. A cross between a blond-haired mother and a red-haired father produced 100% brown-haired children. When they came of age, one child married a double heterozygote, and both were blessed with 7 children; 2 with black hair, 2 with brown hair, 1 with blond hair, and 2 with red hair. TIP: Black hair is homozygous while brown hair is heterozygous, thus represented together in determining the ratio and written as black/brown in the 9:3:3:1 ratio.
