- 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.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?please help me I can't find answers for these questions: here is the link for the article https://www.pbs.org/wgbh/nova/transcripts/2805cancer.html What type of substances are angiostatin and endostatin and where are they produced?

- There is a benign congenital condition called Hereditary Persistence of Fetal Hemoglobin (HPFH) in which production of the fetal hemoglobin (HbF) is not switched off post-partum (after birth). It is due to a mutation in the β-globin gene cluster. People that are homozygotes for this mutation, meaning that the gene from both parents is mutated, continue to make almost exclusively HbF throughout their life rather than adult hemoglobin (HbA). HPFH homozygotes demonstrate a slight erythrocytosis, or an increase in the number or mass of their red blood cells, and consequently an increase in the concentration of HbF. Given only what you know about the oxygen saturation dynamics of HbF versus HbA, can you explain why there might be the slight erythrocytosis in HPFH homozygotes? It has been observed that the prevalence of HPFH is much higher in populations with certain hemoglobinopathic disorders such as sickle cell anemia, and is selected for in populations with a high prevalence of these…How are the genes in the beta-globin locus different from each other? A) They have different evolutionary origins, from different ancestral genes. B) They have different sequences and locations on the chromosome. (C) They are expressed at different times in developmnent. (D) Some are expressed in all cells; some are expressed only in red blood cells. E) They are dispersed on on different chromosomes.What is the frequency of sickle cell disease (anemia)? https://ghr.nlm.nih.gov/condition/sickle-cell-disease#inheritance https://www.cdc.gov/ncbddd/sicklecell/traits.html
