prophase
Chromosomes become visible, nuclear membrane dissolves, spindle fibers forms
metaphase
Chromosomes line up in the middle of the cell
anaphase
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
telophase
Phase of mitosis in which a nuclear membrane reforms around each new set of chromosomes.
cytokinesis
Division of the cytoplasm during cell division
centromere
Area where the chromatids of a chromosome are attached
spindle fiber
help pull apart the cell during replication and are made up of micrtubules
chromosome
A threadlike, gene-carrying structure found in the nucleus. Each chromosome consists of one very long DNA molecule and associated proteins.
chromatid
one of two identical "sister" parts of a duplicated chromosome
Cell cycle
A regulated, continuous sequence of preparation (interphase) and division (mitosis) in a cell
Interphase
Cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases
G1
In interphase - cell grows rapidly, builds new organelles.
S phase
The "synthesis" phase of the cell cycle; the portion of interphase during which DNA is replicated.
G2
Further growth and cell multiplication
Mitosis
Cell's division (PMAT) of the nucleus. Final product is 2 cells that are genetically identical to the parent cell.
What phase of the cell cycle takes the longest
Interphase
What structure holds the two chromatids together
centromere
Which phase does the nuclear membrane dissolve
prophase
What structure moves the chromosomes into position and then pulls them apart
spindle
Chromatin
Loose or relaxed DNA. Not during cell division
