Textbook Question
Chapter 15, Problem 25CTQ
A scientist observes that a cell has an RNA polymerase deficiency that prevents if from making proteins. Describe three additional observations that would together support the conclusion that a defect in RNA polymerase I activity, and not problems with the other polymerases, causes the defect.
