What is a chromosome?
100
The common name for a disease characterized by the uncontrolled cell division.
What is cancer?

What is apoptosis?
200
The creation of identical offspring from a single parent.
What is asexual reproduction?
200
A unique type of body cell that has the ability to divide and renew themselves for long periods of time and remain in undifferentiated in form, and develop into a variety of specialized cell types.
What is a stem cell?
300
The process that divides the cell cytoplasm.
What is Cytokinesis?
300
A complete set of identical chromosomes are positioned at each pole of the cell. The nuclear membranes start to form, the chromosomes begin to uncoil, and the spindle fibers fall apart.

Anaphase
What is the third step of Mitosis?
400
The structures that form at the ends of DNA that are made of repeating nucleotides that do not form genes.
What are telomeres?
400
When the cancer cells break away and spread throughout the body.
What is metastasis?
400
Strawberries, banana plants, and potatoes reproduce this way
What is vegetative reproduction?
400
The process by which unspecialized cells develop their mature forms and functions.
What is cell differentiation?
500
Metaphase
What is the second step of Mitosis?

A group of proteins that organizes and condenses long strands of DNA into tight coils.
What are histones?
500
A broad group of proteins that stimulate cell divisions.
What is growth factor?
500
It is advantageous in changing environmental conditions.
What is sexual reproduction?
500
