You are a cancer geneticist studying dragons and are concerned when several individuals become ill later in life. Some of these dragons are in the same family and you think there might be a genetic component to their illness and you suspect an issue with a tumor suppressor gene. As you investigate, you determine that the issue could be caused by errors in one of the following: 1) eukaryotic transcriptional regulation, 2) a DNA repair mechanism, or 3) from mutations. Provide complete information as an example of how each (for a total of 3) could result in cancer. Be sure to explain specifically how each process could cause cancer. For example: when describing the processes, you should be specific (so don't speak generally about DNA repair, rather discuss with specific details how errors in a particular type of repair would cause cancer). Be thorough in your descriptions and be sure to relate back to the phenotype (having cancer as a result of something to do with this tumor suppressor gene). You may use diagrams or drawing to help with your explanations!
