Stages of Cell Cycle
What is cytokinesis?
Cell cytoplasm divides
What is chromatin?
Long, thin fibers of DNA and proteins
What is telophase?
Chromosomes are unwinding and become enclosed in the nucleus, and the cell begins to divide
Chromosomes before mitosis = 46. Chromosomes at end of mitosis in each cell =
46
What is a cell plate?
Plant cells use this to divide
What is the S phase?
DNA replicates
What is a sister chromatid?
One half of a duplicated chromosome
What is metaphase?
Chromosomes are lined up on the cell's equator
Chromosomes before mieosis = 46. Chromosomes at end of mitosis in each cell =
23
What is a cleavage furrow?
Animal cells use this to divide
What is the G1 phase?
The cell grows and carries out normal activities after division has occurred
What is a centromere?
Holds two sister chromatids together
What is prophase?
The cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the cell
Times cell divides in each cell cycle during mitosis
once
What is binary fission?
Prokaryotes divide this way
What is interphase?
The stage that includes G1, S, and G2
What is a chromosome?
Visible structure seen beginning in prophase
What is anaphase?
Chromatids are pulled apart and become individual chromosomes
Times cell divides in each cell cycle during mitosis
Twice
What are mitosis and cytokinesis?
Eukaryotes use these two steps to divide
What is the G2 phase?
Cell preparation for division occurs
What is DNA?
Nucleic acid that makes up the bulk of a chromosome
What is prophase?
Spindle fibers appear and attach to centromeres
How many chromatids in a chromosome
2
What is cancer?
Uncontrolled cell growth
