![]() There are 23 pairs of chromosomes in a diploid human body cell. Only two pairs of chromosomes are shown in the diagrams below. over when the chromatids stop moving and are gathered at each end of the cell. the sister chromatids separate and begin to move apart. the centromeres become attached to the spindle. Kinetochore microtubules shorten, pulling sister chromatids to opposite poles, polar microtubules elongate, lengthening dividing cell. the centromeres of the duplicated chromosome line up across the center of the wall. Microtubules align chromosomes along metaphase plate. This single substep of Prophase is further subdivided into 5 stages, namely - Leptotene, Zygotene, Pachytene Diplotene, and Diakinesis. Nuclear membrane breaks down, chromatin condenses, mitotic spindle forms and attaches to kinetochores. DNA is replicated during the S phase of Interphase Prophase. It is comprised of G1, S, and G2 stages of the cell cycle. The Prophase of Meiosis is quite long and more complex than the Prophase of Mitosis. Mitosis in a Nutshell The stages of the cell cycle can be broken down into six stages: o Interphase, Prophase, Metaphase, Anaphase, Telophase Interphase Is the 'resting' or non-mitotic portion of the cell cycle. The stages of mitosis are: prophase, metaphase, anaphase and telophase. Metaphase II Anaphase II Telophase II Cytokinesis II Meiosis I - Prophase I : This is the first step in the process of Meiosis cell division. ![]() The cell membrane pinches in and eventually divides into two daughter cells. New membranes form around the chromosomes at each end of the cell. The membrane around the nucleus disappears.Ĭhromosomes and their copies line up in the middle of the cell.Ĭhromosomes and their copies are pulled to different ends of the cell. The DNA in chromosomes and their copies condenses to become more visible.

Most of the time a cell is in interphase, the growth and preparation stage of the cycle. The DNA in chromosomes copies itself ready for mitosis. E-prophase, D-metaphase, B-anaphase, C-telophase. Sie besteht aus Prophase 1, Metaphase 1, Anaphase 1 und Telophase 1. The M phase is broken down into 4 sub-phases: Prophase, Metaphase, Anaphase. Grundsätzlich findet sie in zwei Abschnitten statt. Telophase starts when the chromosomes reach the pole. The chromatids split at the centromere during anaphase. A spindle tube connects the chromosome to the centromere. The nucleolus and nuclear membrane vanish after the prophase stage. The cell spends most of its life in this phase. cell cycle consists of 3 phases: interphase, m phase, and cytokinesis. Prophase, prometaphase, metaphase, anaphase, and telophase are the stages of mitosis. Every base pair of their DNA is identical. The daughter cells are clones of each other. Mitosis is a type of cell division in which a diploid body cell copies itself and finally divides into two identical diploid daughter cells.
