Stages of Cell Cycle
Cell Cytoplasm divides
What is Cytokinesis?
Long thin fibers of DNA and protiens
What is Chromatin?
Chromosomes are unwinding and becoming enclosed in the nucleus, and the cell begins to divide.
What is Telophase?
Chromosomes before mitosis = 46. Chromosomes at end of mitosis in each cell =
What is 46?
DNA replicates
What is Synthesis?
One half of a duplicated chromosome
What is a sister chromatid?
Chromosomes are lined up on the cell's equator.
What is Metaphase?
Cells produced.
What is 2?
The cell grows and carries out normal activities after division has occured
What is the Gap 1 Phase?
Holds two sister chromatids together
What is a centromere?
The cells chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the walls.
What is Prophase.
Times cell divides in each cell cycle.
What is once?
The phase that includes G1, S, and G2.
What is interphase?
Visible structure seen, beginning in prophase.
What is a chromosome?
Chromatids are pulled apart and become individual chromosomes.
Nuclei if cell doesn't finish cytokinesis?
What is 2?
Cell preparation for division occurs
What is the Gap 2 phase?
Nucleic acid that makes up a bulk of the chromosome.
What is DNA?
Spindle fibers appear and attach to centromeres.
What is prophase?
How many chromatids in a chromosome.
What is 2?
