Overloaded
100
Name for relaxed state of DNA
Chromatin
100
Phase which takes up 90% of a cell's time.
Interphase
100
Phase during which chromosomes are lined up across center of cell.
Metaphase
100
Normal cells will form this type of layer in petri dish.
Single
200
Becomes less efficient as cell becomes larger.
Exchange of materials
200
When DNA is duplicate in cell cycle.
S phase of interphase
200
Main activity of G-1 phase of Interphase
Cell growth
200
Phase during which chromosomes are separated.
Anaphase
200
Group of proteins which regulates cell cycle in eukaryotic cells.
Cyclins
300
Realtionship between these two qualities of a cell changes as it grows.
Surface area and volume.
300
Name for each strand of DNA in chromosome
Sister chromatid
300
Main activity of G-2 phase of Interphase
Prepare for mitosis
300
Phase during which spindles form.
Prophase
300
A disorder in which a body's own cells lose the ability to regulate their growth cycle.
Cancer
400
Cell growth triggers this when cell becomes too large.
Cell division
400
"Button" in center of chromosome.
Centromere
400
Process of division of a cell's nucleus.
Mitosis
400
Phase which runs concurrently with cytokinesis.
Telophase
400
Ends of chromosomes which help to regulate how many times a normal cell divides.
Telomeres
500
As a cell grows, the ratio between surface area and volume becomes____________________.
Smaller
500
How many chromosomes does a human have in their body (somatic) cells?
46
500
Process of division of a cell's cytoplasm.
Cytokinesis
500
Longest phase of mitosis.
Prophase
500
Length of time cancer cells will continue to divide.
Indefinitely (unless removed from organism and destroyed or organisms dies, which kills cancer cells.)
