Answer:
According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.
Explanation:
G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.
G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.
Answer: Option D
Explanation:
The bacteria can undergo cell differentiation in response to the environmental conditions.
The oxidative stress, antibiotic exposure, stress conditions are some of the external conditions due to which the bacterial cell can respond in the cell differentiation.
The bacterial species can divide based in the conditions in which they are put. So it is true that under stress conditions the bacterial cell can undergo cell differentiation.
