Many people think that bones in our bodies are dead. This is understandable, since we associate bones with graveyards, Halloween and leftovers. What explanation can you give your younger brother or sister that this is true or not true?

Mutants and mutant genes, 5 points You are studying a gene in chickens named “boneless”, named after its mutant phenotype. The wild type boneless gene encodes a protein that is 400 amino acids long. When a chicken lacks a wild type copy of the gene (in other words, when both of its copies are the boneless mutant version), it grows as a jiggly blob with eyes floating on top.

(A) The wild type function of the boneless gene is most likely to make ________________.

(B)To detect where boneless is expressed during embryogenesis you decide to perform an in situ hybridization experiment with a fluorescently labeled probe. To make this probe, what would you use as the template? Circle your answer and explain in one sentence why your answer is the better of the two choices.

(1) genomic DNA of boneless, which includes 4 exons and 3 introns (2) cDNA of boneless

(C) Given the phenotype of boneless, what can you conclude about the kind of gene that boneless encodes: (circle the correct answer)

(1) it must be a transcription factor (e.g. like pax6) (2) it must be a receptor (e.g. like the insulin receptor) (3) it must encode a calcium channel protein for strong bones (4) it must encode a microRNA gene (5) it must encode a housekeeping gene (6) nothing can be concluded about what kind of product this gene encodes based its mutant phenotype

(D) Although flies do not have bones, you discover that flies have a homolog of boneless called “puddle”. What must be true about puddle?

(1) flies don’t need bones, therefore they have a puddle gene (2) flies lack bones because they lack boneless (3) the puddle gene makes flies boneless (4) puddle and boneless are sequences that arose from a common ancestral gene

1) Bones vary in mechanical properties. Where on the range ofmechanical properties for bone do you think this bone would fall?Address at least elastic modulus, yield stress, and yield orultimate strain.

2) What is a good cross-sectional shape for this bone? Youshould be as specific as you can be, but it is not necessary to bequantitative. That is, you should describe any relevant aspects ofshape, symmetry, thickness, etc. that you think contribute in ameaningful way to cross-sectional area and moment of inertia. Howshould these be different from or similar to what you see in otherbones in other animals?, You don
