Detailed explanation-1: -As a cell expands in volume, its surface area/volume ratio diminishes, resulting in slowed transfer of gases and nutrients. In order to avoid these issues with size, a cell grows and eventually divides to form two “daughter” cells, each with its own complete copy of DNA.
Detailed explanation-2: -The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.
Detailed explanation-3: -During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
Detailed explanation-4: -The cell cycle of a eukaryotic cell has three stages: interphase, mitosis, and cytokinesis. The first stage of the cell cycle is called interphase. During interphase, the cell grows and makes copies of its chromosomes and organelles.
