The alpha-keratin of hair is rich in the amino acid cysteine. The location of these cysteines in the protein chain is genetically determined. As a result of the location of the cysteines in the protein, a person may have curly, wavy, or straight hair. How can the location of cysteines in a-keratin result in these different styles of hair? Propose a hypothesis to explain how a “perm” causes straight hair to become curly

Neurofibromatosis type 1 (NF1) is an inherited is an inheritent dominant disorder. The phenotype usually involves the production of many skin neurofibromas. Answer the following questions about the disorder: a) Are the NF1 neurofibromatosis-causing mutations that are inherited by affected children from affected parents likely to be loss-of-function or gain-of-function mutations? b) Neurofibromin, the protein product of NF1, is associated with the Ras protein. Ras is involved in the transduction of extracellular signals from growth factors. The active form of Ras is complexed with GTP; the inactive form is complexed with GDP. Would the wild-type neurofibromin protein favor the formation of Ras-GTP or Ras-GDP? c) Which of the following events in a normal cell from an individual inheriting a neurofibromatosis-causing allele could cause the descendents of that cell to turn into a neurofibroma? i. A second point mutation in…
Hurler syndrome is due to a mutation in a gene that encodes aprotein called α-l-iduronidase. This protein functions withinlysosomes as an enzyme that breaks down mucopolysaccharides(a type of polysaccharide that has many acidic groups attached).When this enzyme is defective, excessive amounts of the mucopolysaccharides dermatan sulfate and heparin sulfate accumulatewithin the lysosomes, especially in liver cells and connectivetissue cells. This accumulation leads to symptoms such as anenlarged liver and spleen, bone abnormalities, corneal clouding,heart problems, and severe neurological problems. The pedigreebelow contains three members affected with Hurler syndrome,indicated with black symbols. Based on this pedigree, does thissyndrome appear to follow autosomal recessive, autosomaldominant, X-linked recessive, or X-linked dominant inheritance?Explain your reasoning.
