One way in which small viruses package more information into a very small genome is to use overlapping genes so that the same base sequence is read in more than one reading frame.

Why don't hormones build up in the body over time?
A. They are secreted from the body by exocrine glands. B. They are filtered out of the blood by lymph tissues. C. They do, but target tissues become desensitized over time. D. They are degraded by enzymes in the target tissue.
How is glucose involved in catabolite repression of the lac operon?
A) Glucose causes cAMP levels to increase, which leads to increased CRP binding and the lac operon is activated even when lactose is present. B) Glucose causes cAMP levels to decrease, which leads to decreased CRP binding and the lac operon is repressed even when lactose is present. C) Glucose is also a substrate for ?-galactosidase and thus competes with lactose for this enzyme. D) Glucose activates transcription of the lacI gene to increase the amount of Lac repressor in the cell.
