Q.9 Under stress conditions bacteria accumulate (A) ppGpp (Guanosine tetraphosphate) (B) pppGpp (Guanosine pentaphosphate) (C) both ppGpp and pppGpp (D) either ppGpp or pppGpp
Q.9 Under stress conditions bacteria accumulate
(A) ppGpp (Guanosine tetraphosphate)
(B) pppGpp (Guanosine pentaphosphate)
(C) both ppGpp and pppGpp
(D) either ppGpp or pppGpp
Answer
Answer: (A) ppGpp (Guanosine tetraphosphate)
Under stress conditions, such as nutrient limitation, bacteria accumulate ppGpp, not pppGpp. ppGpp is a signaling molecule that helps regulate the bacterial stress response. pppGpp is less common and not typically associated with stress responses in bacteria.
