Definition
- Adjective:
- Relating to mitosis: Pertaining to or characteristic of the process of mitosis, the type of cell division that results in two genetically identical daughter cells from a single parent cell.
- Undergoing mitosis: Describing a cell that is in the process of dividing via mitosis.
Usage
- The term mitotic is used primarily in biological and medical contexts to describe processes, phases, structures, or cells associated with mitosis.
- It functions as a descriptive adjective and is typically placed before a noun (e.g., mitotic spindle, mitotic cell) or after a linking verb (e.g., The cell is mitotic).
Examples
- Adjective:
- The mitotic spindle is crucial for chromosome segregation during cell division.
- Researchers observed a high mitotic index in the tumor tissue, indicating rapid cell proliferation.
- During prophase, the chromosomes condense and become visible under a mitotic microscope.
Advanced Usage
"Mitotic figure": A cell that is visibly in one of the stages of mitosis (prophase, metaphase, anaphase, or telophase), often counted in histopathology to assess the rate of cell division in tissues, especially tumors.
- The pathologist noted several mitotic figures per high-power field in the biopsy sample.
"Mitotic catastrophe": A mechanism of cell death that occurs due to premature or inappropriate entry into mitosis, often triggered by DNA damage or faulty cell cycle checkpoints.
- The chemotherapy drug aims to induce mitotic catastrophe in the cancer cells.
Variants and Related Words
Mitosis (n): The process of nuclear division in eukaryotic cells.
- Mitosis is followed by cytokinesis, the division of the cytoplasm.
Mitotically (adv): In a manner relating to or by means of mitosis.
- The tissue grows mitotically active after injury.
Premitotic (adj): Occurring or existing before mitosis.
- Postmitotic (adj): Occurring or existing after mitosis; often describes cells that have exited the cell cycle and ceased dividing (e.g., neurons).
Synonyms
- Karyokinetic (adj): Relating to the division of a cell nucleus. (Note: This is a more technical and less common synonym.)
Antonyms
- Meiotic (adj): Relating to meiosis, the type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes.
- Amitotic (adj): Relating to or characterized by cell division that does not involve the typical process of mitosis.
