Question
Chapter 14.5, Problem 2.3RIA
Summary Introduction
The stringent response is a stress response that occurs in bacteria when they are starved for amino acids, fatty acid limitation, iron limitation, heat shock, and other stress conditions. It is regulated by guanosine tetraphosphate (ppGpp) which is a second messenger. The stringent response causes a decrease in transcription of rRNA and tRNA and increases the transcription of the biosynthetic genes of amino acids.

xplain the four stages of the growth curve for a microorganism. What is the generation time? Which aspect of the growth curve is used to calculate the generation time and why? How is the generation time calculated and why does it make sense that E.coli and M.tuberculosis have such drastically different generation times?
