1B. (3 pts) Briefly describe an experiment that you could do to test your hypothesis.

Light Waves? In class you were asked to observe an unusual biological phenomenon (e.g. a black lemur self-anointing with a millipede) and then hypothesize what you thought could be happening.  Time to do that again, only this time with the phenomenon of bioluminescent waves.   In some parts of the ocean humans can see a mysterious glow.  This glow is usually intensified by movement; swimming, surfing, or boating through it makes the glow more intense.  Scientists have discovered that the glow is caused by dinoflagellates living in the water. Dinoflagellates float near the surface of the sea where they make a living via photosynthesis and the ingestion of other types of phytoplankton; dinoflagellates in turn get eaten by copepods, small marine crustaceans. Dinoflagellates have special structures called scintillons inside their vacuoles that generate this light using an enzyme called luciferase.  Generating this eerie blue-green light costs energy and resources. Interestingly, they only generate this light at night and only in response to motion. 

Which of the following would you not expect to be possessed by a bacterial cell?

(12 pts) Biomolecules Short Answer Section:   On the structure of the peptide hormone below… A. (3 pts) Identify all the alpha carbons (for example: 16, 18, 23, 28, 32) B. (3 pts) Identify all peptide bonds.  Write the two atoms with a hyphen (‘-‘) connecting them. (for example: 16-17, 21-22, 26-27) C. (3 pts) Identify the N-terminus and the C-terminus, in that order (for example: K, Z) D. (3 pts) Identify the side chains (R groups) of all the amino acids (for example: L, P, S, V). (Note: This question is NOT asking you to write the name of the amino acid, just indicate which letter(s) correspond to amino acid side chains).

Which of the following is NOT a basic assumption underlying Darwin’s mechanism for natural selection?

Week 8: Genetic Technology (12 pts) You make a cDNA library (collection of cDNAs in plasmids) from a rattlesnake’s venom gland cells. Which of the following sentences are TRUE?

Which of the following is NOT a falsifiable and/or testable statement?

Which of the following pairings of a biological macromolecule and the type of bond used to join its major subunits into the final molecule is INCORRECT?

You complete the calculation and determine that z = 0.45 or 45% Frequency of each recombinant gamete = z/2 Frequency of each parental (non-recombinant) gamete = (1–z)/2
