Cell Cycle Vocabulary
Sequence of events in which a cell grows, prepares for division, and divides to form two daughter cells.
What is the Cell cycle?
The reason for cell division or why we need mitosis?
What are Growth and repair?
Uncontrolled cell growth
What is Cancer?

What is Anaphase?
The scientific idea that: 1. cells are the basic unit of life, 2. all cells come from other cells and 3. all living organisms are composed of cells
What is Cell Theory?
The "catch all" term for G1, S and G2
What is Interphase?
What essential (and time consuming) process that is key to mitosis occurs during prophase (not pro-metaphase)?
What is chromosome (or chromatin) condensation?
A substance that can cause mutations to a cells DNA (not normal replication errors)
What is "carcinogen" (will accept "mutagen")?

What is Telophase?
These cells are the important rapidly dividing cells that give rise to new cells in embryos and adult tissues.
What are Stem cells?
The shortest part of the cell cycle. Comes from Greek for "cell" and "cut"
What is Cytokinesis?
This term describes undifferentiated embryonic stem cells.
What is Pluripotent? (or totipotent)
The relationship between adult stem cell division rate and the lifetime risk of cancer in cell types.
What is "increasing mitotic divisions leads to increased risk"? Various answer accepted....

What is Metaphase?
This is the term to describe "programmed cell death", which occurs when a cell is aging or mistakes have occurred in division (like mutations)
What is Apoptosis?
The stage where the nucleus divides into two new identical nuclei.
What is Mitosis?
The stage of the cell cycle where the DNA is being copied in preparation for cell division
What is Synthesis?
This gene/protein is responsible for promoting apoptosis when mistakes occur during cell division
What is p53?

What is prophase?
long protein structures in cells responsible for the cytoskeletal support as well as movement, like movement of chromosomes in mitosis.
What are microtubules?
The process by which cells become specialized for certain functions and structure and lose their ability to become different cell types.
Forms of radiation capable of penetrating our skin or even deeper tissues and damaging the DNA of our cells
Accepted: What is short wavelength radiation? What is gamma, X-ray, UV, etc?
The general terms for the genes (and the proteins they code for) that act as the "brake and gas pedals" for cell division
What are tumor suppressor and proto-oncogenes?

What is Interphase?
The parallel stage in the normal cycle when a cell is no longer actively growing or dividing and has (temporarily or permanently) left the cycle.
What is G0 ?
