158726464 | Multicellular organisms depend on cell division for: | Development from a fertilized cell Growth Repair | |
158726465 | gametes | Nonidentical daughter cells (aka sperm and egg cells) In terms of DNA | |
158726466 | genome | All the DNA in a cell. A genome can consist of a single DNA molecule (prokaryotic) or multiple (euky) | |
158726467 | chromosomes | What DNA molecules in a cell are packaged into | |
158726468 | Somatic cells | (nonreproductive cells) have two sets of chromosomes | |
158726469 | How many chromosomes are in gametes? | Gametes (reproductive cells: sperm and eggs) have half as many chromosomes as somatic cells | |
158726470 | chromatin | a complex of DNA and protein that condenses during cell division | |
158726471 | sister chromatids | Each duplicated chromosome has two sister chromatids, which separate during cell division | |
158726472 | centromere | the narrow "waist" of the duplicated chromosome, where the two chromatids are most closely attached | |
158726473 | Mitosis | Division of the nucleus | |
158726474 | Cytokinesis | Division of the cytoplasm | |
158726475 | Eukaryotic cell division consist of what two stages? | Mitosis and Cytokinesis. | |
158726476 | Meiosis | A variation of cell division by which gametes are produced. | |
158726477 | What is the product of meiosis? | Meiosis yields nonidentical daughter cells | |
158726478 | How many sets of chromosomes do meiotic daughter cells have? | One set, which is half as many as the parent cell | |
158726479 | The cell cycle consists of | Mitotic (M) phase (mitosis and cytokinesis) Interphase (cell growth and copying of chromosomes in preparation for cell division) | |
158726480 | What takes place in M phase? | Mitosis and Cytokinesis | |
158726481 | What takes place in interphase? | Cell growth and copying of chromosomes in preparation for cell division. | |
158726482 | What are the three subphases of interphase? | G1 ("first gap"), S ("synthesis"), and G2 ("second gap" | |
158726483 | The cell grows in what phases of interphase? | All three phases | |
158726484 | What phases of interphase are chromosomes duplicated? | The S phase | |
158726485 | What are the fives phases of mitosis? | PP MAT Prophase, Prometaphase, Metaphase, Anaphase, Telophase | |
158726486 | Cytokinesis occurs in what phase of mitosis? | Telophase | |
158726487 | Describe G2 of Interphase | 1. Nuclear Envelope is formed, 2. Two centrosomes are formed via replication, 3. Chromosomes are not yet condensed | |
158726488 | Describe Prophase | 1. Chromatin fibers condense into chromosomes made of sister chromatids, 2. Nucleoi disappear, 3. Mitotic Spindle begins formation 4. Centrosomes move away from each other | |
158726489 | Describe Prometaphase | 1. Nuclear Envelope Fragments, 2. Microtubles of spindle invade nuclear area, 3. Chromosomes more condensed and have a kinetochore, 4. Kinetochore and nonkinetochore microtubules | |
158726490 | Describe Metaphase | 1.Longest stage, 2. Opposite Centrosomes, 3. Chromosomes line up on metaphase plate, 4. Tubules attached to kinetochore | |
158726491 | Describe Anaphase | 1. Shortest stage, 2. Daughter Chromosomes are seperated | |
158726492 | Telophase | 1. Two daughter nuclei form, 2. Nuclear envelopes and Nucleoi appear, 3. Chromosomes less condensed | |
158726493 | Cytokinesis | Division of cytoplasm well under way by late telophase, daughter cells appear shortly after mitosis. Cleavage furrow pinches cells in two. | |
158726494 | centrosome | the microtubule organizing center | |
158726495 | aster | a radial array of short microtubules that extends from each centrosome | |
158726496 | What composes the mitotic spindle? | The centromsome, the aster, and the microtubules | |
158726497 | kinetochores | protein structure located a centromere of daughter chromosomes | |
158726498 | What occurs during cytokinesis in plant cells? | A cell plate is formed | |
158726499 | Binary Fission | Prokaryotes (bacteria and archaea) reproduce by a type of cell division called binary fission. The chromosome replicates and two daughter chromosomes actively move apart | |
158726500 | origin of replication | In binary fission, the chromosome replicates (beginning at the origin of replication), and the two daughter chromosomes actively move apart | |
158726501 | cell cycle control system | The sequential events of the cell cycle are directed by a distinct cell cycle control system, which is similar to a clock. The cell cycle control system is regulated by both internal and external controls. The clock has specific checkpoints where the cell cycle stops until a go-ahead signal is received | |
158726502 | What is the most important cell checkpoint? | G1 | |
158726503 | What happens if cell does not receive G1 checkpoint clearance? | Switch to nondividing state G0 phase |
