Which pair is correct?
|
|
M phase, cell growth
|
|
|
G2 Phase preparation for mitosis
|
|
|
S phase cell division
|
|
|
G1 phase DNA replication
|
Explanation:
Detailed explanation-1: -During the second gap phase, or G 2start subscript, 2, end subscript phase, the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.
Detailed explanation-2: -The G2-phase checkpoint, also known as G2/M-phase checkpoint, has the function of preventing cells with damaged DNA, lasting from the G1 and S phases or generated in G2, from undergoing mitosis. The mechanisms acting during the G2-phase checkpoint converge on the inhibition of the mitotic complex CDK1-cyclin B.
Detailed explanation-3: -Hence the correct sequence of phases of cell cycle is: G1
