Cell Cycle
G1- Growth; S- Synthesis of DNA; G2- Grow again and prepare to divide
What are the subphases of interphase?
Prophase Metaphase Anaphase Telophase
Prophase Metaphase Anaphase TelophaseWhat are the four stages of mitosis?
a disorder in which body cells lose the ability to control growth (cells go through mitosis uncontrolled)
What is cancer?
This is when cancer cells spread throughout the body and form new tumors.
What is metastasis?
This is the name of proteins used to regulate the cell cycle.
What are cyclins?
This phase lasts the longest (the cell spends most of its time in this phase)
What is interphase?
1. nuclear envelope disappears 2. chromosomes thicken and become visible 3. centrioles start to move to opposite ends 4. spindle fibers begin to form
What are things that happen during prophase?
environmental carcinogens
mutated genes
What are causes of cancer?
These are the two types of tumors.
What are benign and malignant.
These are the two types of regulator proteins.
What are internal regulators and external regulators.
This a stop along the cell cycle to make sure there are no mutations.
What is a checkpoint?
In this stage, sister chromatids separate.
What is anaphase?
Don’t respond to signals and divide uncontrollably.
What are cancer cells?
This type of tumor is cancerous.
What is malignant.
chemotherapy, radiation therapy, surgery, and hormone therapy
What are the main treatments for cancer?
Some organelles are duplicated during this stage of interphase.
What is G2?
This phase of the cell cycle divides the cytoplasm for two identical cells.
What is Cytokinesis?
This is the study of cancer
What is Oncology?
The cell's "self-destruct button" is known as this.
What is apoptosis?
cigarettes, aspartame, and other harmful, cancer-causing chemicals
What are carcinogens?
You expect the amount of DNA to change during this stage of the cell cycle.
What is S phase?
A production of 2 new daughter cells that are identical to the parents cell
What is the result of Mitosis?
Cancer cells form a mass called this
What is a tumor?
A great number of cancer cells have a defect in something called p53, which is this.
What is a gene?
This is a normal gene which when altered by mutation can contribute to cancer
What is a proto-oncogene?
