BIO 301 Mitosis and Cell Division (Hickman Zoology - Chapter 3,5)
| Question | Answer |
|---|---|
| Body Cells | Somatic Cells |
| A term 'reductional division' is used by biologist to describe | Meiosis |
| Mitosis is the only reproductive mechanism if cells undergo... | Asexual Division |
| Complex of DNA with associated protein is known as... | Chromatin |
| A complex body, spherical or rod shaped, that arises from the nuclear network during mitosis, splits longitudinally, and carries a part of the organism's genetic information as genes composed of DNA associated with proteins | Chromosome |
| A localized constriction in a characteristic position on a chromosome, bearing of kinetochore | Centromere |
| Microtubule organizing center in nuclear division... | Centrosome |
| An active cytoplasmic organelle found in the centrosome && division center of the animal cell && organizes spindle fibers during mitosis and meiosis | Centriole |
| Morphological Characteristic of chromosomes... | varies in shape - bent && rod like && mixed shape |
| Disk of proteins that binds with microtubule... | Kinetochore |
| Each chromosome has... | thousands of genes |
| What is current methods of dividing stages of mitosis in simple terms? | Mitosis is artificially divided into four successive stages or phases, although one stage merges into the next without sharp lines of transition |
| Disintegration of nuclear envelope & manufacturing of microtubules &visibility of chromosomes from diffusion of nuclear chromatin happens during... | Prophase |
| Lining up of centromeres with the arms of the sister chromatids happens during the... | Metaphase |
| Disassemblade of microtubules & movement of centrosomes farther apart & relocation of chromosomes towards their respective poles, pulled by kinetochore fibers | Anaphase |
| Disintegration of spindle fibers && formation of daughter chromosomes | Telophase |
