Activity 1: DNA: The Real Deal
A. Using the internet, look up the total length of the DNA from n human cell, in meters. Now multiply this number by the average number of cells in the human body and convert that number to kilometers. Next, look up how far away the Voyager 2 probe is from Earth at this time (in km). Voyager 2 is the most distant human-made device (launched in 1977) If you join all the DNA from your body together, can your reach that probe? Show your work.
B. Describe the results of your attempt at extracting DNA from your kitchen.
Activity 2: Looking for Variation at the Molecular Level
C. So, who is the guilty suspect? Why does the analysis include the victim's blood?
D. Your typical crime-solving shows frequently depict DNA fingerprinting as a 5-minute procedure. In fact, even with improvements in technology, it takes somewhat longer. Do a little research and summarize the process as it is actually performed.
Activity 5: The Mathematics of Population Genetics
M. For a one-gene/two allele system, if your population is 1000 individuals, how many total alleles will you have to count?
N. What are the possible genotypes with these two alleles?
P. Is it possible for two populations to have different genotype frequencies yet have the same allelic frequencies? Give an example.
Q. Does the dominance/recessive status of alleles have anything to do with how common it is in the population? Explain.
