What is the main prerequisite for clearance at the g2 checkpoint?
cell has reached a sufficient size
an adequate stockpile of nucleotides
accurate and complete dna replication
proper attachment of mitotic spindle fibers to kinetochores

The correct answer will be option-accurate and complete DNA replication.

Explanation:

The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.

The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.

Thus, option-accurate and complete DNA is the correct answer.

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
