Front 1

Cell Cycle

Back 1

Repeating sequence of cellular growth division during the life of an organism

Front 2

Interphase

Back 2

Period Between two miotic or meiotic divisions of eukaryotic cell during which the cell carries out routine functing copies its DNA, and prepares to divide

Front 3

Five Phases

Back 3

First Growh G1 Phase
Synthesis Phase S
Second Growth G2 Phase
Mitosis
Cytokenesis

Front 4

First Growth G1 Phase

Back 4

Cell Grows Rapidly and carries out routine functions; occupies major function of a cells life; cells that are not dividing stay in this phase (somatic cells) (body can replace them)

Front 5

Sythesis Phase

Back 5

cells DNA is copied; at end each chromosome consists of two chromatids attached at the centromere

Front 6

Second Growth G2 Phase

Back 6

Preparations are made for the nucleus to divide and microtubules are assembled

Front 7

Mitosis

Back 7

Process during cell division in which the nucleus of a cell is divided into two nuclei; Each nucleus ends up with the same number and kinds of chromosomes as the original cell.

Front 8

Cytokenesis

Back 8

Cell division in which cytoplasm divides

Front 9

Cell Growth Checkpoint

Back 9

Makes key decision of whether cells will divide proteins will stimulate the cell to begin S phase. If conditions arent favorable, cells can typically stop the cell cycle at this checkpoint. (Cell Cycle will stop if the cell needs to pass into a resting period). Muscle cells can stay here and never divide

Front 10

DNA Synthesis G2 Checkpoint

Back 10

DNA replica is checked at this point by DNA repair enzymes; if passed, continues onto mitosis (begin molevular process)

Front 11

Mitosis Checkpoint

Back 11

Triggers the exit from mitosis; signlas the beginning of the G1 phase, the major growth period of the cell cycle

Front 12

Cancer

Back 12

Disease characterized by abnormal cell growth
