Whats 20. Sickle-cell anemia results from a point mutation in the HBB gene. The mutation results in the replacement of an amino acid that has a hydrophilic R-group with an amino acid that has a hydrophobic R-group on the exterior of the hemoglobin protein. Such a mutation
would most likely result in altered (A) properties of the molecule as a result of abnormal interactions
between adjacent hemoglobin molecules (B) DNA structure as a result of abnormal hydrogen bonding
between nitrogenous bases (C) fatty acid structure as a result of changes in ionic interactions
between adjacent fatty acid chains (D) protein secondary structure as a result of abnormal hydrophobic interactions between R-groups in the backbone of
the protein.
