- Cystic fibrosis (CF) is an inherited disorder caused by different types of mutations, many of which prevent ions from moving across cell membranes. Normally there are channel proteins that allow passage of the ions, but in patients with one kind of CF these proteins seem odd. Closer examination shows that these proteins display the correct amino acid sequence. However, they fail to do their job. A) Given that the primary structure of the protein is correct, what can you infer about the DNA sequence for the gene coding this protein on this patient, is there a mutation? Explain. B) Why is the primary structure insufficient to guarantee the proper function of the protein?arrow_forwardBRCA1 is mutated in a large percentage of hereditary breast and ovarian cancers. BRCA1 protein serves as a key enzyme in repairing DNA double-strand breaks. More than 800 mutations in the BRCA1 are clinically significant. This collection of mutations include missense mutations, small deletions, and large rearrangements that result in a protein with reduced function or no protein product. BRCA1 functions by interacting with a variety of proteins, such as Rb, Myc, cyclin-dependent kinase (CDK), and Rad50/51. Rb is important for cell cycle arrest; Myc is a transcription factor that activates genes required for cell proliferation; activated CDK promotes cell cycle progression; and Rad50/51 proteins facilitate repair of DNA double-strand breaks. How many of the mutations listed below would lead to excessive cell growth when the cell was either homozygous or heterozygous for the mutation? Increased expression of Myc Constitutively active Rad50/51 A null mutation in Rb Continuous production…arrow_forwardUsing sickle-cell anemia as an example, describe what is meant by a molecular or genetic disease.

- A normal polypeptide and a mutant of the polypeptide were hydrolyzed by an endopeptidase under the same conditions. The normal and mutantpolypeptide differ by one amino acid. The fingerprints of the peptides obtained from the two polypeptides are shown below. What kind of amino acid substitution occurred as a result of the mutation? (That is, is the substituted amino acid more or less polar than the original amino acid? Is its pI lower or higher?) (Hint: Photocopy the fingerprints, cut them out, and overlay them.)arrow_forwardWhat are the three possible effects on the cell (or organism) when a mutation occurs in DNA?
