Cancer
When cells have unregulated growth
What is cancer?
The splitting of the cytoplasm
What is cytokinesis?
This is the longest stage of the cell cycle.
What is interphase?
*2.7 bya is when these cells first developed.
What are eukaryotes?
The gel-like fluid inside a cell
What is cytosol?
Or
What is cytoplasm?
When mitosis does not stop and cells continue to grow on top of one another and form a mass of cells
What is a tumor?
The organelles responsible for producing spindle fibers and pulling chromosomes apart during mitosis.
What are centrioles?
G1, S, and G2 are the 3 parts to this phase of the cell cycle.
What is interphase?
Cells that are very simple and lack organelles with the exception of ribosomes.
What are prokaryotes?
This biological mechanism assists organisms in maintaining stable internal conditions.
What is homeostasis?
A tumor suppressor gene found on chromosome 17
What is p53?
This is the phase of mitosis when chromosomes condense and become visible.
What is prophase?
This is when organelles make copies of themselves.
What is G1 phase?
This organelle was believed to be photosynthetic bacteria before eukaryotic cells arose.
What is a chloroplast?
The movement of water from a high concentration to a low concentration.
What is osmosis?
When p53 detects an error in the cell cycle or a mutation in DNA it causes this cellular event to occur which is known as programmed cell death
What is apoptosis?
This is the phase of mitosis when two new identical daughter cells are formed.
What is telophase?
This is when enzymes are produced to help the cell get ready for mitosis.
What is G2 phase?
The endosymbiotic theory sites these pieces of evidence.
Eukaryotes contain mitochondria and chloroplast which have their own DNA.
A larger prokaryotic cell is believed to have engulfed smaller photosynthetic bacteria and ATP producing bacteria and kept it alive because it was beneficial for its cellular processes.
Eukaryotes are not as old as prokaryotes according to fossil records.
When there is too much of a solute surround the cell this cellular state will occur.
What is hypertonic?
When p53 is mutated, it does not bind DNA correctly. As a consequence this protein is not produced which normally signals the cell cycle to stop if there is a biological defect in the cell.
What is p21?
This biological mechanism is associated with a group of proteins located throughout various parts of the cell cycle to check for errors and stop the cell from dividing if there is a mutation in DNA or another cellular dis function.
What are checkpoints?
When a cell is completely inactive it is in this phase.
What is G0 phase?
This is an example of an organism that is alive today that displays the endosymbiotic theory.
What are termites?
This double bilayer forms the cell membrane and contributes to it's fluid like properties.
What is the phospholipid bilayer?
