Cell Division
Cell Division Vocabulary
Cell Division Vocabulary | Definition |
---|---|
mitosis | Process of asexual reproduction of cells |
cytokinesis | A moment in time when two new cells separate during cell division |
chromosome | A compact section of DNA, found in the nucleus |
centriole | Produce spindle fibers |
chromatid | Thickened strands of copied DNA |
spindle fibers | Produced by the centrioles, attach to the chromosomes at the centromere and pull them apart during anaphase |
genes | A specific sequence of DNA that codes a specific trait |
DNA | deoxyribonucleic acid, found in the nucleus |
chromatin | Long, thin strands of DNA that is found in the nucleus during interphase |
daughter cells | The new cells that are formed by cell division |
cell cycle | The complete life cycle of a cell, included interphase, mitosis/meiosis and cytokinesis |
interphase | Normal functioning stage of the cell, growth and DNA replication happens at the end of this phase |
prophase | First phase of mitosis in which the chromosomes shorten and thicken, nuclear membrane breaks down |
metaphase | Second phase of mitosis, chromosomes line up in the center of the cell, spindle fibers attach to the centromere |
anaphase | Third phase of mitosis, chromosomes separate and are pulled toward the centrioles |
telophase | Fourth phase of mitosis, nuclear membrane reforms, cell membrane pinches inward |
