Determine the correctness or otherwise of the following Assertion (a) and the Reason (r): Assertion: In synchronous culture, majority of the cells move to next phase of the cell cycle simultaneously. Reason: Synchronous culture could be obtained by starving cells for essential nutrient components. Options: (A) both (a) and (r) are true and (r) is the correct reason for (a) (B) both (a) and (r) are true but (r) is not the correct reason for (a) (C) (a) is true but (r) is false (D) (a) is false but (r) is true
Determine the correctness or otherwise of the following Assertion (a) and the Reason (r):
Assertion: In synchronous culture, majority of the cells move to next phase of the cell cycle simultaneously.
Reason: Synchronous culture could be obtained by starving cells for essential nutrient components.
Options:
(A) both (a) and (r) are true and (r) is the correct reason for (a)
(B) both (a) and (r) are true but (r) is not the correct reason for (a)
(C) (a) is true but (r) is false
(D) (a) is false but (r) is true
Answer
Answer: (A) both (a) and (r) are true and (r) is the correct reason for (a)
Explanation: In synchronous culture, cells move to the next phase of the cell cycle simultaneously, and this can be achieved by nutrient starvation, which synchronizes the cells.
