Question 1
Answer: Cell cycle is process during which cell divides to form daughter cells. It involves three stages such as interphase, mitotic phase and cytokinesis. During S-phase of the interphase of cell cycle, DNA is duplicated inside the nucleus and prepare the cell for division.
Question 2
Answer: Most of the cells life cycle is spent in Interphase of the cell cycle. During this period cells grows by duplicating it's DNA and synthesizing all the proteins essential for cell division.
Question 3
Answer: During metaphase of the cell cycle, nuclear envelope is completely lost and the chromosomes align on the centre of the cell forming metaphase plate. The spindle apparatus that binds to kinetochore of the chromosomes cause the chromosomes to align in the centre of the cell.
Question 4
Answer: During anaphase of the cell cycle, chromosomes gets separated due to breakdown of cohesin between sister chromatids. The separated chromosomes are pulled to opposite sides of the cell.
