Chromosomes
100
The longest part of the cell cycle when cells are performing normal functions is called this.
What is interphase?
100
This is the first phase of mitosis where chromosomes condense and the nuclear envelope disappears
What is prophase?
100

These cells contain half the set of chromosomes 

What is haploid cells or n?

100
This is the name of the cell that is formed when a sperm penetrates an egg cell and their nuclei fuse.
What is a zygote.
100

DNA forms this X like structure during cell division

What is a chromosome

200
In this phase a cell will copy its DNA.
What is Synthesis or S Phase.
200
The daughter cells from mitosis are genetically _____ as compared to the parent cell.
What is identical?
200
This is the name scientists give to the daughter cells produced in meiosis. (not sperm or egg)
What are gametes?
200

This form of reproduction forms genetically identical offspring 

What is asexual reproduction

200

DNA coils tightly around these proteins as it condenses 

What are histone proteins?

300
Before the cell will enter mitosis, the cell performs these to look for errors.
What are checkpoints?
300
This occurs after telophase, when the cell divides the cytoplasm and other organelles.
What is cytokinesis.
300
This is the phase in which crossing over occurs.
What is prophase 1
300
A human zygote has ___ number of chromosomes.
What is 2n or 46.
300

These are the two main parts to a chromosome.

What are centromeres and sister chromatids? 

400
A cell that has errors in the cell cycle or ignores signals to stop dividing or to die may form this.
What is cancer?
400
In this phase, the spindle fibers retract, pulling the chromatids apart.
What is anaphase.
400
When two chromosomes that code for the same genetic information are paired, it is called this.
What is a homologous pair or tetrad.
400

This process unites 2 gametes together

What is sexual reproduction?

400

Two of the same chromosome are known as?

What are homologous chromosomes?

500
A cell may enter this resting phase where it is not dividing.
What is G0.
500

Three cells that undergo mitosis?

What is skin, stomach lining, hair, etc.

500

This is a result of crossing over and recombination in meiosis.

What is genetic variation.

500

Cells that divide using this method have genetic variation 

What is crossing over or meiosis 

500

When chromosomes fail to seperate properly

What is nondisjunction?
