Cell Cycle and Cell Division

Telophase - 5

The chromosomes uncoil into chromatin

Telophase - 5

A new nuclear membrane forms around each set of unraveling chromosomes

Telophase - 5

Forms two identical nuclei

Cytokinesis - 6

Following the last phase of mitosis a cell’s cytoplasm divides in this process

Cytokinesis - 6

In animal cells, the cell membrane pinches inward around the middle of the cell, dividing it in two

Prophase - 2

the copied chromatin (DNA) condenses into chromosomes, coiling together tightly

Prophase - 2

the nuclear membrane breaks down, spindle fibers form in the cytoplasm

Daughter Cells - 7

the result of the cell cycle

Interphase - 1

the DNA is called chromatin during this phase

Chromatin

long thin strands of DNA

Interphase - 1

looks like a plate of spaghetti

Metaphase - 3

Spindle fibers attach to the centromere of each pair of sister chromatids and align the duplicated chromosomes to the middle of the cell

Anaphase - 4

spindle fibers shorten, pulling the sister chromatids towards opposite ends of the cell

Anaphase - 4

each pole of the cell has a complete set of chromosomes

Cell Cycle

Most cells in an organism go through a cycle of growth, development, and division

Interphase - 1

the period during the cell cycle of a cell’s growth and development

Interphase - 1

This period makes up roughly 90% of the cell’s lifespan

Mitosis and Cytokinesis

The last 10% of a cell’s life

Mitosis and Cytokinesis

Creates two new identical cells (daughter cells) and the original cell no longer exists

P.M.A.T.

Prophase

Metaphase

Anaphase

Telophase

Mitosis

the nucleus and its contents divide

Cytokinesis - 6

the cytoplasm and it’s contents divide

Daughter Cells

the two new cell that result from mitosis and cytokinesis

Mitosis Stages of Division

P.M.A.T.

The number of chromosomes in a human’s body

23 pairs (46 total)

copy, organelle

Before a cell divides it makes a ____ of each _________

Mitochondria and Chloroplasts

have their own DNA and can make copies of themselves on their own

Cytokinesis - 6

Prophase - 2

Interphase - 1

Daughter Cells - 7

Telophase - 5

Anaphase - 4

Metaphase - 3

chromosomes

DNA is called ___________ once it has coiled up
