17.2 Evolution as Genetic Change in Populations
INSTRUCTIONS: For each of the following key concepts write a
question. It may be a multiple choice or completion question.
Explain how natural selection affects single-gene and polygenic tr
A virus/phage can integrate its genome into the DNA of a host cell.
Virus either under go:
o Lytic Cycle
Where the phage injects DNA/RNA into the cell.
It gets incorporated into the Genome of the Bacterium
Or go right into the Lytic Cycle and make mor
A Stem Cell will arise from a single cell that will undergo self renewal or something else.
o Each daughter cell can either:
Remain a stem cell and divide indefinitely.
This is not a cancer cell even though cancer cells divide
Mitosis and Meiosis in Human Sex Cells
There are two general kinds of cells in the human body:
o "Body" cells
Ones that aren't in the sexual organs
Mitosis but no meiosis
o Genetic mutations in somatic cells are not passed along to the pr
Proto-oncogenes and oncogenes.
o A normal gene that is not a cancer gene, they are just genes that are doing their
But when mutated, it can promote cancer.
A normal gene that can become an oncogene due to mutation
Example of the Effects of Point Mutation:
Naturally occurring mutations in E.Coli.
o Since the mutant cant make histidine, it can only grow if histidine is added.
There is a histidine synthesis enzyme, where it has one point mutation,
DNA damage and replication mistakes can happen.
o What to do about it?
Repair the mistakes:
In order to repair the mistake, you have to have proteins that are going to
tell the cell to go into cell cycle arrest.
o Some examples of DNA repair
Independent assortment after one complete meiosis:
The point is that after two different times the products are going to be different.
o Starting out meiosis, everything is lined up in the metaphase plate of meiosis I.
First the nucleus breaks down and
o Programmed Cell Death
Where a cell is programmed to die at certain time.
o Cell Suicide.

Why have apoptosis?
Cell Necrosis is ugly and messy. It generates all sorts of garbage.

In general, cancer cells have proteins with:
o Growth signals:
Two type of Growth Signal:
Ignore inhibitory growth signals (tumor suppressors)
o That tells the cell to stop growing.
o If you mutate a tumor suppressor, you ignore this inhibitory
Beginning of Meiotic Prophase I:
Compacted meiotic chromosomes become visible
