what are the steps take place in both mitosis and meiosis?

In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, but the second round is more like mitosis. In mitosis, prophase, metaphase, anaphase and telophase occur once. Chromosomes condense and the centrosomes begin to form an early spindle.

For example, prior to undergoing meiosis, a cell goes through an interphase period in which it grows, replicates its chromosomes, and checks all of its systems to ensure that it is ready to divide. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase.

Meiosis occurs in two stages, called meiosis I and meiosis II, each of which occurs in four phases (prophase, metaphase, anaphase, and telophase). Gametogenesis is the process in which the diploid cells change into mature gametes.

The major difference between meiosis II and mitosis is the ploidy of the starting cell. Meiosis II begins with two haploid cells, which have half the number of chromosomes as somatic cells. This is because they will develop into gametes. Mitosis begins with a diploid cell.

During interphase, the cell grows, performs routine life processes, and prepares to divide. The mitotic phase of the cell cycle in an eukaryotic cell occurs in two major steps: mitosis, when the nucleus divides; and cytokinesis, when the cytoplasm divides and two daughter cells form.

Mitosis and meiosis both involve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development.

Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division). Most of the differences between the processes occur during Meiosis I.

Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase. Before a cell can enter the active phases of mitosis, however, it must go through a period known as interphase, during which it grows and produces the various proteins necessary for division.

The mitotic phase follows interphase. Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into daughter nuclei. Usually the cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.

Meiosis I is a reductional division i.e No of chromosomes are halved in daughter cells. Mitosis is an equational division and the no of chromosomes remain same in both daughter and parent cells. ... Mitosis involves no such crossing over. Centromere splits in mitosis but not in meiosis.

Answer and Explanation: Mitosis takes place in somatic cells and produces two diploid daughter cells. Meiosis takes place in gametic cells and it produces four haploid daughter cells with varied genetic composition (due to crossing over and independent assortment of chromosomes).

Both mitosis and meiosis are processes of cell division. They use the same steps for cell division, including prophase, metaphase, anaphase and telophase. ... The resulting offspring is genetically different in the case of meiosis, while the offspring is identical in the case of mitosis.

During cell replication, mitosis and meiosis follow the same phases: prophase, metaphase, anaphase, and telophase (although meiosis goes through each step twice, while mitosis only goes through each step once).

The two main stages of cell division are mitosis and cytokinesis.

Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell.

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. ... These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase.

Daughter Cells in Mitosis Mitosis is the stage of the cell cycle that involves the division of the cell nucleus and the separation of chromosomes. The division process is not complete until after cytokinesis, when the cytoplasm is divided and two distinct daughter cells are formed.
