mitosis
|
the stage during which the cell's nucleus divides into two new nuclei
|
|
|
PMAT
|
the abbreviation for the phases of Mitosis: prophase, metaphase, anaphase, telophase |
|
|
chromatids
|
identical strands of the chromosomes
|
|
|
cytokinesis
|
the stage when two new daughter cells are formed; final stage of cell cycle during which the cytoplasm divides

|
|
deoxyribose and phosphate
|
alternating sugars that make up the sides of the DNA ladder
|
|
|
DNA replication
|
process in which a cell makes a copy of the DNA in its nucleus to ensure that each daughter cell produced in the cell cycle has the genetic information it needs for the cell to function
|
|
|
chromosome
|
doubled rod of condensed chromatin
|
|
|
centromere
|
holds the two chromatids together at the center
|
|
|
prophase
|
when the spindle fibers form a bridge between the ends of the cell; the threadlike chromatin in the cell's nucleus begins to condense into tiny rods; 1st phase of mitosis
|
|
|
metaphase
|
chromosomes line up across the center (middle) of the cell
|
|
|
anaphase
|
chromatids move to opposite ends and begin to pull away from one another
|
|
|
telophase
|
nuclear membrane forms around chromosomes; final phase of mitosis
