one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope
What is a centriole?
100
Before cell division occurs, the cell replicates, or copies, all of its DNA.
What happens during interphase?
100
G1, S, and G2.
What are the main stages of the cell cycle?/What are the phases of the cell cycle associated with interphase?.
100
disorder in which some of the body's own cells lose the ability to control growth
What is cancer?
100
part of eukaryotic cell division during which the cell nucleus divides
What is mitosis?
200
process by which a cell divides into two new daughter cells
What is cytokinesis?
200
This replication of DNA solves the problem of information storage because each daughter cell gets one complete set of genetic information. Thus, each daughter cell receives its own genetic “library.”
How is a cell's DNA like the books in a library?
200
What is the 4th and final stage of the cell cycle (before the cell actually splits)?
What is mitosis?
200
Cancer cells break apart and spread to other parts of the body.
What is metastasize?
200
first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
What is prophase?
300
one of two identical “sister” parts of a duplicated chromosome
What is chromatid?
300
Each daughter cell has an increased ratio of surface area to volume.
As a cell increases in size, which increases more rapidly, its surface area or its volume?
300
DNA is "synthesized" or made during this stage.
What is S phase or "synthesis"?
300
Programmed cell death or destruction.
What is apoptosis?
300
Chromosomes align along the equator of the cell. Second stage of mitosis.
What is metaphase?
400
area where the chromatids of a chromosome are attached
What is the centromere?
400
Cancer cells that remain clustered together.
What is a benign tumor?
400
Made up of DNA,which carries the cell's coded genetic information,and proteins.
What are chromosomes made of?
400
A broad group of proteins that stimulate cell division.
What are growth factors?
400
Chromatids separate toward opposite sides of the cell. Third phase of mitosis.
What is anaphase?
500
fanlike microtubule structure that helps separate the chromosomes during mitosis
What is a spindle fiber?
500
Before it becomes too large, a growing cell divides forming two “daughter” cells.
What is cytokinesis?
500
In most prokaryotes, the rest of the process of cell division is a simple matter of separating the contents of the cell into two parts.
What is binary fission?
500
Agents that may increase the risk of cancer.
What are carcinogens?
500
fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material
