AP Biology - Unit 4 - The Cell Cycle

series of events in which a cell grows, lives, and replicates

Cells with jobs, specialized characteristics (ex. skin cells, heart cells, brain cells)

found in bone marrow, immature cells, not yet differentiated

The physical process of cell division, cytoplasm divides into two daughter cells

Cell division, results in two identical daughter cells, 5 phases (interphase, prophase, metaphase, anaphase, telophase)

most of the cells life

Cell grows

DNA and Centrisomes are replicated (interphase)

Final phase

cell suicide

nuclear membrane disintegrates

The second stage of mitosis

the doubled chromosomes

chromosomes split in half and move to opposite sides of the cell; the cell membrane begins to pinch at the center

cell membrane finished constricting

Section of DNA

Protein that DNA is coiled around for packaging

histone-DNA complex

Many nucleosomes wrapped together

Chromosomes 1-22 (human)

chromosome 23

band that attaches the sister chromatids together

a complex of proteins associated with the centromere of a chromosome during cell division

A cell containing two sets of chromosomes

A cell containing only one set of chromosomes

the process of adding a phosphate group to a molecule

regulates the cell cycle by phosphorylating the proteins that trigger cell reproduction

formation of new blood vessels

the spread of cancer cells beyond their original part of the body

the process that stops healthy cells from dividing when there is not an open space

Cells with mutations in the genes that control the cell cycle
