100

Cell Cytoplasm divides

What is Cytokinesis?

100

Long thin fibers of DNA and protiens

What is Chromatin?

100

Chromosomes are unwinding and becoming enclosed in the nucleus, and the cell begins to divide.

What is Telophase?

100

Chromosomes before mitosis = 46. Chromosomes at end of mitosis in each cell =

What is 46?

200

DNA replicates

What is Synthesis?

200

One half of a duplicated chromosome

What is a sister chromatid?

200

Chromosomes are lined up on the cell's equator.

What is Metaphase?

200

Cells produced.

What is 2?

300

The cell grows and carries out normal activities after division has occured

What is the Gap 1 Phase?

300

Holds two sister chromatids together

What is a centromere?

300

The cells chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the walls.

What is Prophase.

300

Times cell divides in each cell cycle.

What is once?

400

The phase that includes G1, S, and G2.

What is interphase?


400

Visible structure seen, beginning in prophase.

What is a chromosome?

400

Chromatids are pulled apart and become individual chromosomes.

What is anaphase?
400

Nuclei if cell doesn't finish cytokinesis?

What is 2?

500

Cell preparation for division occurs

What is the Gap 2 phase?


500

Nucleic acid that makes up a bulk of the chromosome.

What is DNA?

500

Spindle fibers appear and attach to centromeres.

What is prophase?

500

How many chromatids in a chromosome.

What is 2?
