Term
|
Definition
| All the DNA in a cell constitutes the cell's |
|
|
Term
|
Definition
| What the DNA molecules in a cell are packed into |
|
|
Term
|
Definition
| (non-reproductive cells) have two sets of chromosomes |
|
|
Term
|
Definition
| (reproductive cells: sperm and eggs)have half as many chromosomes as somatic cells |
|
|
Term
|
Definition
| A complex of DNA and protein that condenses during cell division |
|
|
Term
|
Definition
|

|
|
Term
|
Definition
| The division of the nucleus. |
|
|
Term
|
Definition
| The division of the cytoplasm |
|
|
Term
|
Definition
| Gametes are produced by a variation of cell division |
|
|
Term
|
Definition
| Mitotic (M) Phase (mitosis and cytokinesis), Interphase (Cell growth and copying of chromosomes in preparation for cell division) |
|
|
Term
|
Definition
| G1 phase (first gap), S phase (synthesis), g2 phase (second gap) |
|
|
Term
|
Definition
| Prophase, Prometaphase, Metaphase, Anaphase, Telophase |
|
|
Term
|
Definition
| Chromatin begins to condense, individual chromosomes become visible. |
|
|
Term
|
Definition
| Nuclear envelope breaks down, spindle fibers attach to the chromosomes centromere. |
|
|
Term
|
Definition
| Chromosomes line up right down the middle, on the metaphase plate |
|
|
Term
|
Definition
| Kinetochores of the chromatids separate at the centromere, move to the side of the cell. |
|
|
Term
|
Definition
| Spindles disappear, nuclear envelope forms around the two chromosomes on each side of the cell |
|
|
Term
|
Definition
| An apparatus of microtubules that controls chromosome movement during mitosis |
|
|
Term
|
Definition
| The microtubule organizing center |
|
|
Term
|
Definition
| Radial array of short microtubules |
|
|
Term
|
Definition
| The midway point between the spindle's two poles |
|
|
Term
|
Definition
| Creates cleaveage to split a cell in half |
|
|
Term
|
Definition
| Prokaryotes reproduced by this type of cell division |
|
|
Term
| Describe the structural organization of the prokaryotic genome and the eukaryotic genome |
|
Definition
| Prokaryotic genome is often a single DNA molecule, eukaryotic genomes usually consist of a number of DNA molecules |
|
|
Term
| List the phases for the cell cycle; describe the sequence of events during each phase |
|
Definition
| G1 phase (cell grows), S phase (duplication of chromosomes), g2 phase (growth of cell), Mitotic phase (separates cells) |
|
|
Term
| List the phases of mitosis and describe the events characteristic of each phase |
|
Definition
| Prophase (condense, see chromosomes), Prometaphase (nuclear envelope leaves, spindles attach), Metaphase (lines chromosomes up along the metaphase plate), Anaphase (Chromosomes split, get pulled to side of cell), Telophase (nuclear envelope surrounds kinectochores on each side of cell, separate the cell) |
|
|
Term
| Compare cytokinesis in animals and plants |
|
Definition
| Cytokinesis in animals occurs with a cleavage furrow, in plants they create a cell wall to split the two cells. |
