Ageneticist discovers an obese mouse in his ca laboratory colony. he breeds this obese mouse with a normal mouse. all the f1 mice from this cross are normal in size. when he interbreeds two f1 mice, eight of the f2 mice are normal in size and two are obese. the geneticist then intercrosses two of his obese mice, and he finds that all of the progeny from this cross are obese. these results lead the geneticist to conclude that obesity in mice results from a recessive allele. a second geneticist at a laboratory in ny also discovers an obese mouse in her laboratory colony. she carries out the same crosses as those done by the first geneticist and obtains the same results. she also concludes that obesity in mice results from a recessive allele. the geneticists meet and share their mice with each other. they both find that when they cross an obese ca mouse with an obese ny mouse, all the offspring are normal. explain their results.

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
