fast answer **Question:**Which of the following best describes the anaphase checkpoint?**Options:**- Verifies that cells are large enough to divide before exiting G1- Verifies that DNA has been completely replicated before exiting S-phase- Verifies that chromosomes are properly attached to opposite poles- Verifies that the nuclear envelope has properly re-formed- Verifies that cytokinesis has been properly completed

Interphase: During the cell division DNA duplicates and grow cell in interphase. It is the main component of the cell cycle. Interphase is divide into three phases. G1 phase (gap phase) S phase (synthesis phase) G2 phase (second gap phase)G1 phase is the first phase of the interphase. In this phase, the cell grows in size for the preparation of mitosis. It also increases the number of proteins and organelles. S phase is also known as the synthesis phase. In this phase, DNA is copied. So there is an extra copy of DNA present. G2 phase is the second gap phase. In this phase, the cell continues to grow for cell division.In this process when one phase is completed then it moves to the next phase but moving toward the next phase there is a checkpoint present. It checks for DNA error, resources, and cell sizes. The checkpoints, the cell “checks” to make sure everything is operating correctly. There are two checkpoints in interphase. The first checkpoint present between G1 and S phase and the second checkpoint present between G2 and the division of the cell.G1 checkpoint work during the G1 phase. In this checkpoint, the cell has to be check that the cell grows properly and prepare for cell division. G2 checkpoint work after DNA replication. It checks that no replication error occurs. After interphase cells start to divide physically.Anaphase checkpoint verifies that chromosomes are properly attached to opposite poles. Anaphase is the cell cycle that comes after metaphase and this stage has a role in centromere splitting and chromatids separation, and moving of chromatids to opposite poles. Cells have a tendency that before going to any further phase they first check and verify at the checkpoints and then only proceed further to the next stage. The anaphase checkpoint verifies that chromosomes are properly attached to opposite poles.
