Then the duplicate strands of DNA move to opposite sides of the cell. First the DNA replicates and the cell grows to twice its normal size. Simple organisms such as bacteria undergo a type of cell division called binary fission. The splitting of the cells is called cytokinesis or cell cleavage. The two new cells, or daughter cells, are formed. These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). The cell walls then pinch off and split down the middle. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. ![]() Generally, anaphase I involve separating the. In this stage of meiosis, since there is no DNA replication in between, the diploid cell with two alleles for each gene gets reduced to a haploid cell containing a single allele at each gene.
