|
Mitosis
|
division of a cell's nucleus that produces two new cells with the same DNA
|
|
|
Meiosis
|
nuclear division that produces 4 cells with half the number of chromosomes (haploid), produces sperm and egg
|
|
|
Interphase
|
cell carries out its functions.Split into 3 phases: (G1)
(S) (G2) |
|
|
Metaphase
|
spindle fibers attach to centromeres. Chromosomes form a line in middle of cell
|
|
|
Telophase
|
2 nuclei are made. The spindle dissolves and the chromosomes uncoil.
|
|
|
Prophase
|
Membrane dissolves and chromosomes coil up. The spindle fibers then form
|
|
|
Anaphase
|
Chromatids separate and move to opposite sides of cell. Chromatids are now chromosomes
|
|
|
Cytokinesis
|
Last step in cell cycle. Cytoplasm splits and forms two of the same cell
|
|
|
Chromosome
|
The DNA and its proteins
|
|
|
Chromatid
|
The two copies of DNA that make up a chromosome during the process of mitosis
|
|
|
Centromere
|
Place on chromosome where the chromatids are attached
|
|
|
Zygote
|
First diploid cell containing DNA from both parents
|
|
|
Gamete
|
Cells formed by Meiosis that contain the organisms haploid number of chromosomes.
|
|
|
Crossing over
|
when parts of a chromatid on a homologous chromosome switch places with a part of another chromatid on the opposite homologous chromosome
|
|
|
Spindle fibers
|
structures in a cell that are involved in moving chromosomes during the division of the cell.
|
|
|
Diploid
|
Cell that contains both sets of homologous chromosomes
|
|
|
Cancer
|
Unregulated cell growth
|
|
|
Haploid
|
cell that contains one set of chromosomes
|
|
|
Somatic cell
|
all body cells besides germ cells and gametes. produces identical cells in mitosis.
|
|
|
DNA
|
stores genetic information in gene form
|
|
|
Autosomes
|
chromosomes that don't determine the sex of an individual
|
|
|
Homologous chromosomes
|
pair of chromosomes that carry the same genes
|
|
|
Spindle
|
structure that binds to the chromosome and separates during cell division
|
|
|
Centrosome
|
organelle that produces the spindle during cell division
|
|
|
Asexual reproduction
|
offspring is identical to parent
|
|
|
Sexual reproduction
|
offspring are genetically different from parents
|
|
|
fertilization
|
the action or process of fertilizing an egg
|
|
|
ovules
|
female sex cells
|
|
|
pollen
|
male sex cells
|
|
|
Interkinesis
|
Interkinesis is a period of rest that cells of some species enter during meiosis
|
