100
Cell cytoplasm divides
What is cytokinesis?
100
Long, thin fibers of DNA and proteins
What is chromatin?
100
Chromosomes are unwinding and become 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?
100
Plant cells use this to divide
What is a cell plate?
200

Spindle fibers hold sister chromatids in place at the center of the cell

What is the metaphase?

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

At the end of the cell cycle the number of cells produced

What is 2?

200
Animal cells use this to divide
What is a cleavage furrow?
300
The cell grows and carries out normal activities after division has occurred
What is the G1 phase?
300
Holds two sister chromatids together
What is a centromere?
300
The cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the cell
What is prophase?
300
Times cell divides in each cell cycle
What is once?
300
Prokaryotes divide this way
What is binary fission?
400

The stage that includes growth, DNA replication and preparing to divide

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

Number of hours it takes a human liver cell to reproduce

What is 22?

400
Eukaryotes use these two steps to divide
What are mitosis and cytokinesis?
500

Forming two nuclei at opposite ends of the cell

What is the telophase?

500
Nucleic acid that makes up the bulk of a chromosome
What is DNA?
500
Spindle fibers appear and attach to centromeres
What is prophase?
500
How many chromatids in a chromosome
