Review 10 Flashcards
In order of Mitosis to happened what has to be copied?
DNA copying
What has to be divided inside the cell?
cytoplasmic divided
Main difference in plant division
do not have centrioles and formation of cell plate
Uncontrollable division of cells is called
Cancer
As the cell becomes larger 2 things grow
Volume and Surface area
(Volume grows faster)
As the cell gets larger, what happeneds to the SA and V ratio?
It decreases
Why does a cell need to divide?
when its too big and hard time with diffusion
If the DNA is not copied before division the 2 new cells will be
different
In what stage in Mitosis/Pmat do chromosomes line up in the middle?
Metaphase
When are chromosomes visible?
cell division
What happens during interphase?
The period of growth
Cancers make masses that are called
tumors
What proteins help control the timing of the cell cycle
cyclins
What are spindles made of
cytoskeleton
What are a few ways to fight cancer
chemotherapy
chemoradiation
surgery
What type of tumor does not spread through the body
benign
What type of tumor spreads through the body
malignant
cell cycle
living growth phase and division phase
Apoptosis
Cells that die by self destrustion
When is DNA replicated?
S phase
Stem cells
ability to differentiate
When do cells stop growing?
When they come in contact with other cells
When do cells become specialized
cell differentiation
cytokinesis
division of the cytoplasm
cancer cells have a defect in the __________ gene that regulates the cell cycle
p53 gene
When egg and cell meet the first cell is called the
zygote
carcinoma is a type of
skin cancer
