Lab 5: Meiosis Pre-Lab Questions What major events occur during the interphase? Answer: The cell functions at its job, and prepares for mitosis by collecting resources and duplicating organelles (G1) and genetic content (S), then creating proteins needed for nuclear division (G2). A person, residing in a location where they are exposed to the sun often, develops a mutation in […]
CSI Wildlife, Case 1 Background The scenarios investigated are based on the recently published literature: Wasser, S. K., Brown, L., Mailand, C., Mondol, S., Clark, W., Laurie, C., & Weir, B. S. (2015). Genetic assignment of large seizures of elephant ivory reveals Africa’s major poaching hotspots. Science, 349(6243), 84–87. The underlying data are available on the Dryad Digital Repository: http://dx.doi.org/10.5061/dryad.435p4. Remember, DNA […]
The Hardy-Weinberg Equation 1 How can we make predictions about the characteristics of a population? Why? Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practical to perform a Punnett square analysis on all possible combinations of all members of a population to predict what the population might look like in […]
Lab 4: Enzymes Pre-Lab Questions How could you test to see if an enzyme was completely saturated during an experiment? List three conditions that would alter the activity of an enzyme. Be specific with your explanation. Take a look around your house and identify household products that work by means of an enzyme. Name the products, and indicate how you […]

Bio Genetics: DNA NOTES: Tube Sample Lane 1 1 kb DNA ladder 1 2 Mother’s DNA 2 3 Child’s DNA 3 4 A.F. #1 DNA 4 5 A.F. #2 DNA 5 Record the distance each ladder band moved from the well in mm along with the size of the DNA fragments in that band in bp units, based on the […]
Mendelian Genetics Pre-Lab Questions In a species of mice, brown fur color is dominant to white fur color. When a brown mouse is crossed with a white mouse all of their offspring have brown fur. Why did none of the offspring have white fur? Can a person’s genotype be determined by their phenotype? Why or why not? Are incomplete dominant […]
Population Genetics Pre-Lab Questions Assumptions: There are approximately 3,000,000,000 base pairs in the mammalian genome (genes constitute only a portion of this total). There are approximately 10,000 genes in the mammalian genome. A single gene averages 10,000 base pairs in size. Only 1 out of 3 mutations that occur in a gene result in a change to the protein structure. […]
DNA and RNA Pre-Lab Questions Arrange the following molecules from least to most specific with respect to the original nucleotide sequence: RNA, DNA, Amino Acid, Protein Identify two structural differences between DNA and RNA. Suppose you are performing an experiment in which you must use heat to denature a double helix and create two single-stranded pieces. Based on what you […]
Energy and Photosynthesis Pre-Lab Questions Describe how the functional units for beta carotene, xanthophyll, chlorophyll A, and chlorophyll B are different. Be sure to identify the subunits that adhere to paper during chromatography. Describe a technique for measuring photosynthetic rate. Many deciduous trees have leaves which turn yellow in the fall. What do you suppose is happening in the leaves […]
