Mitosis
DNA Replication
Cancer
100
Cell cytoplasm divides
What is cytokinesis?
100
Long, thin fibers of DNA and proteins
What is chromatin?
100
Chromosomes are unwinding and become enclosed in the nucleus, and the cell begins to divide
What is telophase?
100
What are the three components that make up a nucleotide? 

phosphate group, 5-carbon sugar deoxyribose, and a nitrogenous base

100

Cancer cells divide uncontrollably to form a mass of cells. What is this called? 

a tumor 

200
DNA replicates
What is the S phase?
200
One half of a duplicated chromosome
What is a sister chromatid?
200

Chromosomes are lined up on the cell's equator

What is metaphase?

200

What bases pair together in Chargaff's rule? 

Adenine to Thymine; Cytosine to Guanine

200

What is the main cause of cancer? 

Unregulated or Uncontrolled Cell Division

300
The cell grows and carries out normal activities after division has occurred
What is the G1 phase?
300
Holds two sister chromatids together
What is a centromere?
300
The cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the cell
What is prophase?
300

What is the name of the enzyme that unzips the DNA molecule? 

helicase 

300

_____ is a process of programmed cell death.

Apoptosis

400
The stage that includes G1, S, and G2
What is interphase?
400

Visible structure seen beginning in prophase

What is a chromosome?

400
Chromatids are pulled apart and become individual chromosomes
What is anaphase?
400

What is the name of enzyme that joins the nucleotides back together and proofreads the DNA molecule ?

DNA polymerase

400

Which gene is the most common in cancer cells? 

p53 gene

500
Cell preparation for division occurs
What is the G2 phase?
500
Nucleic acid that makes up the bulk of a chromosome
What is DNA?
500
Spindle fibers appear and attach to centromeres
What is prophase?
500

What type of bond holds the nitrogenous bases together? What type of bond holds the nucleotides together?

Hydrogen bonds hold the bases; Covalent bonds hold the nucleotides.
