Compare and contrast eukaryotic and prokaryotic controls for transcritpion. Which one primarily uses negative control? Positive control? Be specific and make sure to include transcriptional control, post transcriptional control, translational control, and post translational control. (250 word minimum)

In sweet peas, purple flower color (P) is dominant over white (p), but there is also a control gene such that if the plant has a “C”, the purple has “permission” to express itself. If the plant is “cc,” the purple does not “have permission” to express itself and the flower will be white anyway. If a plant with homozygous purple, controlled flowers is crossed with a plant with white, non-controlled flowers, calculate the genotype and phenotype ratios of the F1 and F2 generations.

In a species of plants, axial flowers are dominant to terminal flowers and the trait for height is incompletely dominant. A medium height plant with axial flowers (double heterozygote) is crossed with another double heterozygote plant. What are the genotypic and phenotypic ratio of the offspring?

What are my expectations for this course (Grade in class, AP Score, and WHY!!!)

Hello,
Welcome to AP Biology 2011-12. We look forward to an entertaining but challenging year. This blog will serve as a discussion post and a Q&A with me. I will try to respond to questions within 12-24 hours. Best of Luck!
