B) downregulation of tRNA synthesis
C) ATP
D) GTP
E) no change in gene expression

Question

Quizplus · Accepted Answer

The stringent response is a regulatory mechanism used by bacteria to survive under stressful conditions, such as amino acid starvation. It involves the downregulation of rRNA and tRNA synthesis to conserve resources, and it is mediated by the alarmone guanosine tetraphosphate (ppGpp), which affects the synthesis of these molecules. ATP and GTP are nucleotides involved in energy transfer and protein synthesis, respectively, but the stringent response specifically alters gene expression to adapt to stress, contradicting the option of no change in gene expression.
