Term | Definition |
---|---|
Mitosis | process by which a cell divides it’s nucleus and contents. |
cell cycle | pattern of growth, DNA replication, and cell division that occurs in a eukaryotic cell. |
Cell division | is the process by which a parent cell divides into two or more daughter cells. |
Replication | process by which DNA is copied |
Chromatin | loose combination of DNA and proteins that is present during interphase. |
Chromatid | one half of a duplicated chromosome. |
Chromosome | long continuous thread of DNA that consists of numerous genes and regulatory information. |
Centromere | region of condensed chromosome that looks pinched, where spindle fibers attach during meiosis and mitosis |
Cytokinesis | process by which the cell cytoplasm divides. |
Centrioles | small cylinder-shaped organelle made of protein tubes arranged in a circle; aids mitosis. |
Daughter nuclei | the two nuclei that result from the division of a single cell nucleus usually by mitosis. |
Clone | genetically identical copy of a single gene or an entire organism. |
Diploid (number) | cell that has two copies of each chromosome one from an egg an done from a sperm. |
Asexual reproduction | process by which offspring are produced from a single parent. |
Interphase | the stage in the development of a cell following mitosis or meiosis during which the nucleus is not dividing. |
Cell plate | develops at the midpoint between the two groups of chromosomes in a dividing cell and that is involved in forming the wall between the two new daughter cells. |
Binary fission | asexual reproduction in which a cell divides into two equal parts. |
Grafting | budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant. |
Cancer | common name for a class of diseases characterized by uncontrolled cell division. |
Prophase | first phase of mitosis when chromatin condenses the nuclear envelope breaks down, the nucleolus disappears and the centrosomes and centrioles migrate to opposite sides of the cell. |
