- Cell division (cytokinesis) occurs in a stepwise progression, called mitosis, with four distinct phases (Fig. 1). During prophase the cell nucleus disappears and chromosomes condense. The next step, metaphase, is characterized by the alignment of the cromosomes along the cell's equator.

- mitosis or m phase m M phase is relatively brief and consists of nuclear division (mitosis) and cytoplasmic division (cytokinesis). In mitosis, replicated chromosomes divide, leading to identical daughter nuclei with the same number of chromosomes and the same genetic composition as the parents.

Mitosis, Cell Division and the Cell Cycle Mitosis (M phase), the separation and segregation of chromosomes, occurs in five distinguishable stages (prophase, prometaphase, metaphase, anaphase and telophase), but represents a continuous process in the cell.

The five stages of the cell cycle? he cell cycle consists of four distinct phases: G1 phase, S phase, G2 phase (collectively known as interphase) and M phase. M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's chromosomes are divided between the two daughter cells, and cytokinesis, in which the cell's cytoplasm divides forming distinct cells.

Cell Cycle In eukaryotic cells, this process includes a series of four distinct phases. These phases consist of the Mitosis phase (M), Gap 1 phase (G 1), Synthesis phase (S), and Gap 2 phase (G 2) . The G 1, S, and G 2 phases of the cell cycle are collectively referred to as interphase.

- The phases are in the following sequence: prophase, metaphase, anaphase, and telophase (see figure below). The movement of chromosomes is facilitated by a structure called the mitotic spindle, which consists of microtubules and associated proteins. Spindles extend from centrioles on each of the two sides (or poles) of the cell, attach to the chromosomes and align them, and pull the sister chromatids apart. Chromosomes are usually visible under light microscope. We can determine the number of chromosomes [and chromatid(s) per chromosome] for each stage in mitosis.

Metaphase Metaphase (from the Greek μετά, adjacent and φάσις, stage) is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase).

The Process of Meiosis 1 Meiosis is preceded by interphase which consists of the G1 phase (growth), the S phase (DNA replication), and the G2 phase.  During prophase I, the homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over.

Chromosome The original chromosome and the copy are now called sister chromatids. During metaphase, when a chromosome is in its most condensed state, the X-shape structure is called a metaphase chromosome. In this highly condensed form chromosomes are easiest to distinguish and study.

The Stages of Mitosis and Cell Division During metaphase of mitosis, chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres. During anaphase of mitosis, paired centromeres in each distinct chromosome begin to move apart as daughter chromosomes migrate centromere first toward opposite ends of the cell.

- Observing Mitosis with Fluorescence Microscopy. Anaphase. Almost immediately after the metaphase chromosomes are aligned at the metaphase plate, the two chromatids from each chromosome are pulled apart by the mitotic apparatus and migrate to the opposite spindle poles in a process known as anaphase.

The phase in mitosis where the sister chromatids separate and are pulled by spindle fibers to opposite sides of the cell is the? Metaphase is when chromosomes attatch to spindle fibers in the phase of mitosis.

- The mitotic phase consists of the following stages: 1) Prophase: At prophase (after DNA synthesis is already completed during interphase), the cell is still preparing for division. 2) Metaphase: At the prophase or early metaphase, the spindle tubules start appearing.

Mitosis: function/stages 1 Photographs of early, mid and late prophase stage. 2  Metaphase (meta = mid): the middle phase. 3  At metaphase all chromosomes are completely spiralized and move to the middle of the cell (equatorial plane; see micrographs (made by Dilixiati Hasimu)of a polar and side view of metaphase in a Solanacea).

Metaphase Chromosomes lined up on the metaphase plate. Two views with the metaphase plate rotated 90°. Metaphase (from the Greek μετά, adjacent and φάσις, stage) is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their most condensed and coiled stage.

- Mitosis occurs in four phases. The first phase is prophase. Cells in prophase have an enlarged nucleus, the nucleolus is no longer visible, and the chromosomes appear as short jumbled strands within the nucleus. Cells spend about 14 percent of the cell cycle in prophase. This is the next largest amount of time spent in a phase after interphase.

- Mitosi s is characterized by distinctive steps: prophase, metaphase, anaphase, telophase and cytokinesis. Meiosis is another form of cell division that results in the formation of haploid daughter cells containing a single copy of the chromosome set. This process is important in the formation of gametes. The cell cycle is controlled by an extremely complex pathway of interacting protein signals.

Meiosis Metaphase I. The second phase of meiosis I. the paired homologous chromsomes (tetrads) align at the center of the cell (the metaphase plate). Anaphase I. The third phase of meiosis I. the replicated homologous chromosomes are separated (the tetrad is split) and pulled to opposite sides of the cell. Telophase I Chromosomes move all the way to the other side of the cell and two new cells are ultimately formed.
