Question | Answer |
---|---|
Mitosis | A type of cell division. |
Daughter cell | Cells formed when a cell undergoes cell division by mitosis. |
Meiosis | A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. |
Chromatin | The material of which the chromosomes of organisms other than bacteria are composed. It consists of protein, RNA, and DNA. |
Chromatid | Each of the two threadlike strands into which a chromosome divides longitudinally during cell division. |
Sister Chromatids | Are pieces of identical DNA that are crucial in the process of cell replication and division. |
Chromosomes | Where the DNA is located. |
Homologous chromosomes | Pairs one from each parent that are similar in length, gene position, and centromere location. |
Gene | Transferred from a parent to offspring and is held to determine some characteristic of the offspring. |
Karyotype | The number and visual appearance of the chromosomes in the cell nuclei. |
Centrioles | A minute cylindrical organelle near the nucleus in animal cells. |
Centromere | Where the microtubules of the spindle attach to the chromosomes. |
Centrosome | Contains the centrioles. |
Aster | A star shaped structure formed during division of the nucleus of an animal cell. |
Spindle fibers | Any of a network of filaments that collectively form a mitotic spindle. |
Inter phase | Contains of G1 , M, and G2 |
Prophase | Comes after Inter phase |
Metaphase | After prophase |
Anaphase | After metaphase |
Telophase | After anaphase |
Cytokinesis | During telophase |
nuclear envelope | Membrane which surrounds the genetic material |
Kinetochore Fiber | Protein structure on chromatin where the spindle fibers attach during cell division |
Nucleolus | Where the chromosomes are found |
