Detailed explanation-1: -The purpose of mitosis is to make more diploid cells. It works by copying each chromosome, and then separating the copies to different sides of the cell. That way, when the cell divides down the middle, each new cell gets its own copy of each chromosome.
Detailed explanation-2: -At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells. Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes.
Detailed explanation-3: -The reason why it is important that the product of mitosis, the two daughter cells be genetically identical is to maintain the genetic identity of the somatic cell. Mitosis is a way for the daughter cells to grow and become the same cell type that will perform the same function for that cell.
Detailed explanation-4: -The aim of mitosis is to separate the genome and ensure that the two daughter cells inherit an equal and identical complement of chromosomes (Yanagida 2014).
Detailed explanation-5: -During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
