The Cell Cycle
When a cell goes through the cell cycle what is the end result?
The cell divides and produces two cells ("daughter cells")
During the cell cycle, what percent of the time is a cell in Interphase?
90%
List the phases of mitosis in order.
Prophase, Metaphase, Anaphase, Telophase
True or false: Cytokinesis includes the division of the DNA.
False (this happens during mitosis)
What is the longest phase in the cell cycle?
Interphase
Is the DNA visible as chromosomes during interphase?
No (it is still Chromatin, the chromosomes have not yet formed)
FILL IN THE BLANK: Cytokinesis divides the __________
Cytoplasm
The cell cycle results in two genetically _________ cells.
Identical
Is the nuclear membrane still present during interphase?
Yes
In which phase do the 2 new nuclear envelopes form around the separated chromosomes?
Telophase
During ________________, the cell grows to its full size, copies the DNA and organelles, and prepares to divide.
Interphase
How many cells are produced with each cell cycle (after mitosis & cytokinesis)?
Two
During interphase, _______ is duplicated.
DNA
TRUE/FALSE: In animal cells does the cell membrane get pinched together?
TRUE
Why is the cell cycle important for multicellular organisms?
The cell cycle allows for growth, tissue regeneration and cell replacement.
If a cell has 30 chromosomes, how many chromosomes will each daughter cell have after completing the cell cycle?
30 chromosomes
Spindle fibers attach to the centromeres and the chromosomes line up in the middle of the cell during this phase of mitosis.
Metaphase
In plant cells, a _______________ is built between the two daughter cells as they pull apart during cytokinesis.
Cell plate (cell wall)
