Stages of Cell Cycle
Cell cytoplasm divides
What is cytokinesis?
Long, thin fibers of DNA and proteins
What is chromatin?
Chromosomes are unwinding and become enclosed in the nucleus, and the cell begins to divide
What is telophase?
(True or false) Daughter cells are identical to parent cells
False
Plant cells use this to divide
What is a cell plate?
DNA replicates
What is the S phase?
One half of a duplicated chromosome
What is a sister chromatid?
Chromosomes are lined up on the cell's equator
What is metaphase?
Sister chromosomes are pulled apart
What is anaphase 1?
Animal cells use this to divide
What is a cleavage furrow?
The cell grows and carries out normal activities after division has occurred
What is the G1 phase?
Holds two sister chromatids together
What is a centromere?
The cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the cell
What is prophase?
A source of genetic diversity between sister chromosomes
Crossing over
Prokaryotes divide this way
What is binary fission?
The stage that includes G1, S, and G2
What is interphase?
Visible structure seen beginning in prophase
What is a chromosome?
Sister chromatids are pulled apart and become individual chromosomes
What is anaphase?
True or false: Meiosis is the process by which cells reproduce, grow and repair
False
Eukaryotes use these two steps to divide
What are mitosis and cytokinesis?
Cell preparation for division occurs
What is the G2 phase?
Nucleic acid that makes up the bulk of a chromosome
What is DNA?
Spindle fibers appear and attach to centromeres
What is prophase?
The number of daughter cells produced
What is 4
Uncontrolled cell growth
What is cancer?
