Unformatted text preview: PLANT BIOLOGY 113 Spring 2009 Instructor: Professor S. O’Neill 1 HOMEWORK QUESTIONS #1 (50 points) Please turn in with your Take-Home Exam or to your Discussion Section. 1. List four unique aspects of plant development. Includes, but not limited to . . . A. Alternation of generations B. Double fertilization C. Indeterminate growth pattern D. Plants must adapt to their environment because they are immobile 2. Would you expect the complexity of leaf RNA to be more or less than that of RNA isolated from a bacterial culture of E. coli cells. Explain your answer. □ C R of leaf mRNA would be greater than C R of E. coli mRNA. □ A leaf is composed of several distinct cell types while a pure E. coli culture consists of a single cell type. □ Bacterial cells are less complex than eukaryotic cells. 3. You are interested in characterizing the organization of a specific region of the soybean genome. Specific 1 kb fragments from this genomic region have been cloned. A representative map of this region showing cloned fragments A-F is shown below. Each of these fragments is radioactively labeled and hybridized with a DNA gel blot containing soybean genomic DNA. The results obtained from this experiment are shown below....
