Detailed explanation-1: -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-2: -Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
Detailed explanation-3: -Renewing of damaged cells. Production of new cells from older ones. Maintains the total number of chromosomes. Provides more cells for growth and development.
Detailed explanation-4: -The two types of cell division are mitosis and meiosis. Mitosis results in two genetically identical daughter cells, while meiosis results in four genetically distinct daughter cells. mitosis results in diploid daughter cells, while meiosis results in haploid daughter cells.
