Imagine an animal that shows two variants; one long-legged and one short-legged. Each female produces 2 female offspring per generation and then dies. The offspring of the long-legged ones survive to adulthood (reproductive age) with a probability of 3/5 and the offspring of the short-legged ones survive to adulthood with […]

You should now start preparing for the Applied Final Lab Project itself. This project is based entirely on Lab 4 (Enzymes). While Experiment 2 of Lab 4 is “The Effect of Temperature on Enzyme Activity”, the Final Lab Project is “The Effect of Low pH on Enzyme Activity”. Recall that […]

Dr. Ara B. Dopsis and Dr. C. Ellie Gans are performing genetic crosses on daisy plants. They self-fertilize a blueflowered daisy and grow 100 progeny plants that consist of 55 blue-flowered plants, 22 purple-flowered plants, and 23 white-flowered plants. Dr. Dopsis believes this is the result of segregation of two […]

1. Would two nucleotides at a time be sufficient to provide enough codons to code for all 20 amino acids? Why or why not? How many amino acids could be coded for by codons containing only two nucleotides? 2. Will three nucleotides per codon work? Why or why not? Explain […]
