Cell Division/Reproduction
The place where DNA is stored in a eukaryotic cell.
What is the Nucleus?
The final phase on Mitosis; Chromatids reach poles of the cell; Nuclear envelope forms around chromatids; spindle-fibers dissapear.
What is Telophase?
The first phase of Mitosis in which the cell prepares for the rest of Mitosis. Chromatin coils into Chromosomes; the nuclear envolope dissapears; centrioles move to the poles; spindle-fibers form.
What is Prophase?
Proteins that control the cell cycle by receiving signals on the cell membrane.
What are External Regulatory Proteins?
Cells that fail to stop at required checkpoints and divide too rapidly and live longer than normal cells.
What is Cancer?
A form of reproduction in which 2 parent cells join to form a daughter cell, mixing genetic information and increasing the chance of that species' survival.
What is Sexual Reproduction?
The phase where the chromasomes line up in the middle of the cell and prepare to split.
What is Metaphase?
The stage of a cell's life where it grows and duplicates organelles, copies it's chromasomes, and checks over the duplicated chromosomes.
What is Interphase?
The "place" where Cyclins join with CDK to check if the cell is cleared to continue developing.
What is a Checkpoint?
The adjective placed on a tumor if spread to other parts of the body; meaning viral or evil.
The name of uncoiled, natural state of DNA; name of DNA before it coils into Chromasomes.
What are Chromatins?
The end of Mitosis, where the cell splits into 2 identical daughter cells, which are identical to the parent cell.
What is Cytokinesis?
The name of the coiled state of DNA; Composed of a single mocecule of DNA wraped around protein histones; Condenced cromatin.
What are Chromasomes?
The name of the proteins that regulate the timing of the cell cycle from within the cell.
What are Cyclins?
A mass of abnormal cells that can be cancer-causing if spread to other parts of the body.
What is a Tumor?
The way most unicellular organisms reproduce.
What is Asexual Reproduction?
Daily Double!
The wall surrounding the nucleus; the barrier containing the genetic information of the cell; is not the nucleus, but makes up the nucleus.
What is the Nuclear Envelope?
The two threadlike strands of DNA that compose chromasomes; chromasomes split into these during Anaphase.
What are Chromatids?
The name of one of the three checkpoints where a cell is checked during interphase.
What is the Spindle Assembly Checkpoint; What is the DNA Damage Checkpoint; or What is the Unreplicated DNA Checkpoint?
A process of the removal of tumors through targeted radiation.
What is Chemotherapy?
The proteins that hold DNA while they are bundled into chromosomes.
What are Histones?
The microtubes that extend from the centrioles to seperate the chromatid during cell division.
What are Spindle-Fibers?
The 3rd phase of Mitosis; Centromeres split, leaving sister chromatids to be pulled to opposite ends of the cell.
What is Anaphase?
A protein complex that checks if a cell can continue with the cell cycle.
What is CDK?
Things such as Tobacco, Radiation, and human-made chemicals that can cause DNA damage.
What are Carcinogens?
