Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle : two gap phases G1 and G2 ; an S for synthesis phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides. Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour. The replicated chromosomes are attached to a 'mitotic apparatus' that aligns them and then separates the sister chromatids to produce an even partitioning of the genetic material.

Crossing over is an event that recombines DNA between homologous, non-identical chromosomes. The result is an increase in genetic variation because the resulting daughter cells have slightly different genetic combinations than the original parent cell. Crossing over only occurs during meiosis. This is because homologous chromosomes are only in adjacent positions during prophase I. Crossing over cannot occur during mitosis because this alignment is never present; daughter cells of mitosis are always genetically identical to the parent cell. Sister chromatids separate during anaphase of mitosis and anaphase II of meiosis.

Introduction In order for organisms to grow, cells have two options: they must either replicate themselves to create more cells, or the cells themselves must expand in volume. In humans, tissues such as the skin and blood contain cells that are actively dividing , whilst other tissues such as fat contain cells that expand good if you need energy for winter, bad if you are trying to fit into some expensive jeans. Other cells, such as neurons, will never divide again once they are terminally differentiated; they are post-mitotic. In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? This choice is the choice between mitosis and meiosis.

  1. The correct answer to the question is letter D or DNA replication occurs before the division of the nucleus. They have multiple stages interphase, prophase, metaphase, anaphase, and telophase. Both mitosis and meiosis are involved in DNA replication, as well.
