Conduct this AP Biology Lab. Record your data/calculations. In this experiment you will observe the effects that genetic drift can have on the allele frequency in a populationover time. 1. A population of glacier chipmunks lives in an alpine meadow at the base of a steep mountain. A single genedetermines the […]

Protein kinase transfer the terminal phosphate from ATP to specific serines, threonines or tyrosines of specific target proteins. To test these particular phosphorylation sites we use site-directed mutagenesis to convert the to-be-phosphorylated serines, threonines or tyrosines to aspartic acids or alanines. One of these is considered a non-phosphorylatable mutation and […]

Question 2According to the James-Lange theory of emotion, we feel fear when a) we have learned […]

I spent hours on this problem but I still don’t get it. Most flour beetles are black, but several color variants areknown. Crosses of pure-breeding parents produced the followingresults in the F1 generation, and intercrossing theF1 from each cross gave the ratios shown for theF2 generation. The phenotypes are abbreviated […]
