What is the base pairing rule? 

A->T, C->G

100
This is the process by which a cell makes a copy of the DNA in its nucleus.
What is replication
100

The regular sequence of of growth and division that cells undergo is know as this.

The cell cycle

100

In the phase, the nuclear membranes return, resulting in 2 nuclei but 1 cell. 

Telophase

100
The location of DNA in animal cells.
What is the nucleus?
200

What is the structure of DNA?

Double Helix

200

Which phase of the cell cycle does DNA replication occur in?

S phase of interphase
200

Interphase is composed of 3 phases. What are those 3 phases?

G1, S, G2

200
During this phase of mitosis, the chromosomes line up across the center of the cell, and each chromosome attaches to a spindle fiber at its centromere, which still holds the chromatids together.
What is metaphase?
200

What makes cancer cells different than healthy cells?

cancer cells divide uncontrollably 
300
The scientists that discovered DNA structure are?
Watson & Crick
300
Adenine, Thymine, Cytosine, and Guanine
What are the four nitrogen bases?
300

In what phase of the cell cycle does the nucleus divide? 

Mitosis. 

300
In this phase, the sister chromatids are being pulled apart as spindle fibers shorten.
What is Anaphase?
300
Genetic information is stored in packages of DNA. Humans have 46 pairs of these.
What are chromosomes?
400

What does DNA stand for? 

Deoxyribonucleic Acid

400

Which enzyme is known as the builder and creates the complementary strand of DNA?

DNA Polymerase

400
The phase where cells spend the majority of their time.
What is Interphase?
400

What is the result of mitosis?

2 identical nuclei 

400

What are two reasons cells need to divide? 

Growth & Repair 

500
The sides of the DNA ladder are made of molecules of deoxyribose and this other molecule?
What is phosphate?
500

What is the first step in DNA replication? 

Helicase unzips the dna strand. 

500

What is the result of the cell cycle?

2 identical daughter cells

500

Centrioles migrate to opposite ends of the cell. Spindle fibers form. Nucleus disappears. 

What is prophase?

500

What is programmed cell death called? 

apoptosis
