Lecture 19 Flashcards
What happens if the cells in the intestinal wall die faster than you can replace them?
You get a leaky gut and any toxin/bacteria can come in
What happens when cells divide too fast?
It can be indicative of cancer
What is the cell cycle?
It is the cycle that is responsible for renewal and maintenance of cells
What is the G0 Phase?
Cells that are not prompted by external or internal factors to divide reside here
What is the G1 phase?
Here is where the cell grows in size, makes proteins/organelles, and builds energy for replication
What is the S Phase?
The synthesis phase where the cell replicates its DNA. Makes exact copy of the entire genome
What is the G2 phase?
The final checkpoint before mitosis and divides. The cell grows more and checks for error/damage.
What is the M phase?
The mitosis phase where the cell divides and goes through PMAT. The end result is two identical daughter cells
What is the MAPK pathway?
This is where cells manage to communicate an extracellular signal down into the nucleus to the DNA
What does EGF do?
promotes cell growth
How many bp are in the human genome?
3 billion
What are SNPs?
variation at a single base pair
What create SNPs?
Single base pair substitutions
How many SNPs are there in the human genome?
10 million
What do SNPs do?
Call for variance among people such as appearance, diseases, or responses to drug. The majority have no observable differences
What can SNPs tell about people?
How closely related they are.
