Answers (1)


D. The G1 checkpoint, often referred to as the restriction point, is a cell cycle checkpoint that takes place at the conclusion of the G1 phase. In order to determine if the cell is prepared to enter the S-phase and begin DNA replication, the cell performs a variety of internal and external checks at this checkpoint. This stage examines the presence of sufficient reserves, cell size, and genomic DNA damage. Hence option D is correct.
