Are you SURE?
Going through the cell cycle (not just mitosis)
What is dividing during mitosis?
The nucleus
The process where cytoplasm divides is called...
cytokinesis
A cell spends most of its' lonely life in what phase?
Interphase
Cells formed during mitosis are genticially _______ to the parent cell.
IDENTICAL
The term for a tumor that is considered CANCEROUS is....
Malignant
During which phase of mitosis are the chromosomes aligned in the center of the cell?
Metaphase
What is a centromere?
The round part in the center of a chromosome/connects the chromatids
During which part of the cell cycle does DNA replication occur?
S Phase
TRUE OR FALSE
The main purpose of mitosis is for humans and multicellular organisms to produce offspring.
FALSE. Mitosis is only used in body cells (not connected to reproduction).
TRUE or FALSE
The nucleus is visible during all of mitosis
False
During which stage of mitosis are chromosomes pulled apart and brought to opposite sides of the cell?
Anaphase
What is cancer?
Uncontrolled cell division/a disorder of the cell cycle/uncontrolled cell division
Why doesn't the cell shrink each time it divides?
During Interphase the cell experiences two growth phases so that it has enough cytoplasm
Name 3 reasons that cell division must occur in living things.
Growth, Replacement, Repair(healing
Humans have _____ chromosomes in each of our cells.
46
The end result of mitosis, after cytokinesis is...
Two genetically identical daughter cells.
These peices form and anchors the spindle during mitosis
Centriole/s
What are the stages of the cell cycle in order from G1.
G1, Sphase, G2, Misosis, Cytokinesis
(G0 is acceptable but does not need to be mentioned)
During prophase, the chromosomes are in a replicated, condensed form called
Chromosomes
Cancer always affects the DNA of the organism with cancer.
TRUE or FALSE
TRUE. Cancer only occurs when DNA is damaged, but the cause of the damage can come from genes, exposure to carcinogens, or other mutations.
List all of the phases of Mitosis in order
Prophase, Metaphase, Anaphase, Telophase
These organells attach to chromasomes and pull the chromatids apart during Anaphase ________ _______
Spindle Fibers.
We know that mitosis allows us to GROW. We know that cancer occurs as a result of mutations that occur to DNA during the cell cycle. Who would you expect to have a higher risk of cancer? A tall person or a short person (with everything else being exactly the same).
A TALL person. Tall people have grown more, meaning they have more cells and go through the cell cycle more frequently. This means more risk of mutations & cancer.
When a cell is not in the later stages of mitosis, DNA is in a loose, uncondensed form called
Chromatin
