(For those who have taken the courses and want to submit for evaluation, please read the instructions linked on the table of contents page. Most of the questions below have straightforward answers from the material in the corresponding courses, although a few questions require some further studies, which are still based on the course material.)

  1. Gene ontology are structured as directed acyclic graphs. What would happen if cycles are allowed?
  2. Give biological examples for "is-a" and "part-of" relationships, one for each.
  3. Briefly describe an example of how gene ontology is used in the analysis of DNA microarray data.
