Identical twins have been studied extensively to help us understand the inheritance of traits in humans. We have long believed that the sequence of nucleotides in our genes was the ultimate determinant of protein function. If that is true, what could explain the observations that one identical twin can have asthma but not the other? What about when one identical twin has severe depression and not the other?

A mutation in the promoter region of the gene for the beta-globin can cause betathalassemia, a hereditary condition which causes anemia. Why would mutations in the promoter region lead to low levels of hemoglobin?

What does the protein beta globin do and how many beta globin genes are there?
How can a single nucleotide insertion in the beta globin gene generate a phenotypic change in the ability of the red blood cell to transport oxygen?
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? Explain.
In a floodplain or swampy environment would individuals with a mutation of a decreased ability to withstand temperature changes to an overall decrease in fatty tissue would be or less well adapted to their environment? why?
Based on your understanding of genetic code,explain the formation of any abnormal hemoglobin molecule?
Sickle-cell anemia is a genetic disorder of individuals homozygous for a mutation of hemoglobin that causes their red blood cells to be sickle shaped and stiff under conditions of low pO2. Why is this disease life threatening?
Based on the sensitivity of DNA to DNase I, as illustrated in Figure , which type of chicken hemoglobin (embryonic or adult) is likely to be produced in the highest quantity in the following tissues and developmental stages? Q. Erythroblasts at day 14
A new mother notices that one of her newborn twins has a yellow-orange complexion. Fearful that the child may have jaundice (a condition caused by bilirubin, a toxic yellow-orange pigment produced during the destruction of red blood cells), she takes him to her pediatrician. After examining the child and noting that his bilirubin levels are normal, the pediatrician declares him perfectly healthy and advises the mother to watch the child’s diet. Why? The other twin suffers from bluish coloration of this skin condition known as cyanosis (bluish tint). What can cause cyanosis? 2. Janine was taken to the ER for heat stroke and dehydration. Should she be given IV fluids that are hypertonic, isotonic, or hypotonic to cytosol? Explain your answer. 3. Grayson is receiving a drug treatment transdermally (through the skin). Explain why drugs delivered by this route are fat-soluble rather than water-soluble.
The amino acid at the β82 position is in the central cavity that binds 2,3-bisphosphoglycerate in the deoxygenated form of hemoglobin. How would the mutation of Lys to Asn affect the ability to bind to 2,3-BPG? a. It would have no effect. b. It would have decreased 2,3-BPG binding. c. It would have increased 2,3-BPG binding. d. It would have increased 2,3-BPG binding at least two fold.
