Cell Cycle- Definition, Phases, Regulation and Checkpoints

Cell Cycle

Cell Cycle Definition The cell cycle is the sequence of events occurring in an ordered fashion which results in cell growth and cell division. The cycle begins at the end of each nuclear division and ends with the beginning of the next. A cell cycle acts as a unit of biological time that defines the life history of the cell.  …

Cytokinesis- Definition and Process (in animal and plant cells)

Cytokinesis in plant and animal cells

Cytokinesis Definition Cytokinesis is a physical process of cell division, that normally takes place after mitosis. Cytokinesis is the physical division of the cell cytoplasm, the cell membrane, and cell organelles in eukaryotic cells to produce two distinct cells at the end of the cell cycle in both mitosis and meiosis. In most cells, cytokinesis is initiated during the anaphase …

Telophase in Mitosis and Meiosis (Telophase I, II)

Telophase in Mitosis and Meiosis

What is Telophase? Telophase is the fifth phase of mitosis and the final phase of meiosis as well. In meiosis, there are two phases of telophase I and telophase II. This is the stage of separation of duplicate genetic materials that are carried in the cell nucleus of the parent cells. They end up forming two identical daughter cells. Telophase …

Anaphase in Mitosis and Meiosis (Anaphase I, II)

Anaphase in Mitosis and Meiosis

Anaphase Definition This is the phase that separates duplicate genetic materials that are carried in the nucleus of the parent cell, into the two identical daughter cells. In the previous phase, metaphase, the sister chromatids (replicated chromosomes) are aligned along the cell’s equator on the metaphase plate. Therefore, during anaphase, each pair of chromosomes separates into two identical but independent …

Prophase in mitosis and meiosis (Prophase 1 and 2)

Prophase in mitosis and meiosis (Prophase 1 and 2)

Prophase Definition Prophase is the phase that follows the interphase and typically the first and longest phase in the cell cycle, for both mitosis and meiosis. It is the phase of DNA unwinding and chromatin condensation to make the chromosomes visible. What Happens in Prophase? During prophase, the separation of the DNA that was synthesized in the interphase phase takes …

Interphase- definition, stages, cell cycle, diagram, video

The Stages of Interphase and the Cell Cycle

What is Interphase? Cells continuously undergo cell division through which daughters cells arise which mature and also produce their own daughter cells and the cycle continues. The events of the cell cycle involve cell growth and cell division, of which the interphase defines the phase of cell growth where several metabolic reactions take place. The interphase is the preparation phase …
