100
This increases more rapidly than surface area, causing a cell to need to divide.
What is volume
100
The phase when the chromosomes begin to coil, the nuclear envelope disappears, and the spindle forms.
What is prophase.
100
Humans have 48 of these.
What are chromosomes.
100
This is what happens when cells don't get the signals to stop dividing.
What is cancer.
100
These are formed when cancer cells divide rapidly and form masses of cells.
What are tumors.
200
Two reasons cells divide.
What are DNA overload and not enough surface area to get things in and out.
200
The order of mitosis.
What is prophase, metaphase, anaphase, telophase.
200
This is made up of two sister chromatids.
What is a chromosome.
200
These are the two types of regulators for cell growth.
What are internal and external regulators.
200
Two places where you can find stem cells.
What are human embryos and in our own body (ex: bond marrow)
300
A parent cell has 4 chromosomes. When it divides, this is number of chromosomes each daughter cell will have.
What is 4.
300
The role of the spindle during mitosis.
What is helps separate the chromosomes to opposite poles.
300
The structure connecting two chromatids.
What is a centromere.
300
This is what happens when you have a cut.
What is cells divide to fill empty space around injury.
300
This is what stem cells do.
What is differentiate/become specialized in structure and function into many cell types/cells the body cannot produce after injury or disease
400
The phase (specifically) during which DNA is replicated.
What is S (Synthesis).
400
G1, S, G2 make up this.
What is interphase.
400
DNA that is not tightly packed or coiled. How DNA appears prior to division.
What is chromatin.
400
A way cells know to stop dividing.
What is they touch each other.
400
This is how cancer spreads.
What is cells break off from masses and spread through bloodstream and infect surrounding tissues.
500
When the cytoplasm splits and you have two cells.
What is cytokinesis.
500
Starting with 4 chromatids in the nucleus of the cell, this is the number of chromosomes that will be present in each new nucleus.
What is 2 chromosomes.
500
These help to organize the spindle.
What are centrioles.
500
These regulate the timing of the cell cycle in eukaryotic cells.
What are cyclins.
500
Many cancer cells are thought to have a defect in this gene.
What is p53.
