100
Cell cytoplasm divides
What is cytokinesis?
100
DNA shape
What is double helix?
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
Prokaryotic cells divide in this way
What is binary fission
200
DNA replicates, cell acquires nutrients, longest period of cell life
What is interphase?
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 after mitosis
What is 2?
200
n, n=23, haploid, egg and sperm cells
What is a gamete?
300
4 daughter cells
What is the Meiosis II?
300
Holds two sister chromatids together
What is a centromere?
300

The cell's chromosomes become condense, 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
Eukaryotes divide this way for growing, tissue repair, and replacing old cells
What is mitosis?
400
The stage 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
how many chromosomes in a human gamete
What is 23?
400
Eukaryotes use these two steps to divide their DNA and cytoplasm
What are mitosis and cytokinesis?
500

Cell cycle has two phases

What is the interphase and mitotic cell division?

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
