1. A cellular structure is composed of 2 distinct gene products and a total of 8 polypeptides. How many distinct polypeptides must the structure have?
2. If a plant cell contains 1 nuclei/nucleus (assume 2 membranes), 4 mitochondria (assume 2 membranes), and 4 chloroplasts (assume 3 membranes), how many functionally distinct membranes does this cell have?
3. A cellular structure is composed of 2 polypeptides that have identical sequences and compositions. How many unique gene products are required to form this structure?
