Genetics mothers give birth to sons at the same time at a busy urban hospital. the son of mother 1 is afflicted with hemophilia, a disease caused by an x-linked recessive allele. neither parent has the disease. mother 2 has a normal son, despite the fact that the father has hemophilia. several years later, couple 1 sues the hospital, claiming that these two newborns were swapped in the nursery following their birth. as a genetic counselor, you are called to testify. part awhat information can you provide the jury concerning the allegation? what information can you provide the jury concerning the allegation? passage of x-linked genes typically occurs in a complicated way and the data available can neither support nor deny the first couple's claim. passage of x-linked genes typically occurs from affected parent to affected son. the fact that neither parent from couple 1 has hemophilia suggests that their son could not have the condition. the first couple's claim is valid. passage of x-linked genes typically occurs from affected father to affected son. the fact that the father in couple 2 has hemophilia would ensure his son to have this condition. the first couple's claim is valid. passage of x-linked genes typically occurs from carrier mother to affected son. the fact that the father in couple 2 has hemophilia would not predispose his son to hemophilia. the first couple has no valid claim.

Match the descriptions / definitions with the term they best describe 1. three dimensional relationship of the different polypeptide chains in a multisubunit protein or protein complex 2. common folding pattern in proteins in which a linear sequence of amino acids folds into a right-handed coil stabilized by internal hydrogen-bonding between polypeptide backbone atoms. 3. the amino acid sequence of a protein 4. a region on the surface of a protein that can interact with another molecule through noncovalent bonding. 5. three-dimensional arrangement of alpha-helices and beta-sheets within a single polypeptide, typically stabilized by a variety of noncovalent bonds, including ionic and hydrogen bonds, and nonpolar interactions / hydrophobic force. 6. the chain of repeating carbon and nitrogen atoms, linked by peptide bonds, in a protein. 7. common structural motif in proteins in which different sections of the polypeptide chain run alongside each other and are joined together by hydrogen bonding between atoms of the polypeptide backbone. 8. portion of a polypeptide chain that has a discrete tertiary structure of its own and can often fold independently of the rest of the chain 9. regular local folding patterns in a protein, including alpha-helix and beta-sheet a. primary structure b. beta-sheet c. protein d. coiled-coil e. polypeptide backbone f. secondary structure g. side chain h. tertiary structure i. binding site j. alpha-helix k. quaternary structure l. protein domain
