The amount of dissolved stuff inside a cell versus outside is called...
Tonicity
Plant cells resist bursting due to their (Blank)
Large Vacuole + Rigid Cell Wall
In what field was selective breeding an early bio tech for?
Agriculture
Diffusion moves solutes from...
High to low
Homozygous means that..
I have one dominate and one recessive
Hypotonic means what
Less solutes (more water moves into the cell)
Explain the central dogma of biology
DNA -> RNA -> Proteins
What are the 5 pros to Genetically modify things that we spoke about in class and was on the slides?
1. Make more nutritious food (led to creation of golden rice to combat childhood blindness)
2. Insect Resistance
3. Herbicide Resistance
4. Bigger bodies and Faster growth for animals
5. Feeds more people!
Isotonic means what
Equal Solutes (water moves equally out and in)
A white cow and a Red Cow make a Rean Cow, what is this an example of? Why?
Codominance Shows both
A chromosome is located in the...
Nucleus
What is PCR used for
Genetic testing, personal DNA tests and Genetic Mapping (Human Genome Project), Forensic Testing
what are the 5 CONCERNS that we looked at in class
1. organism that we want to kill will become invincible
2. Organisms that we don't have to kill will be killed
3. Genetically modified crops are not tested regulated adequately
4. eating genetically modified foods is dangerous
5. loss of genetic diversity among crop pants is risky
What is a genome and where is it stored
It is all the DNA letters in your body in a specific order. it is located in chromosomes in your nucleus
What is the percent that baby Jeramiah will NOT have the purple eye syndrome

Put the following in order from smallest to largest:
- Cell
- Gene
- Chromosome
- Nucleus
Gene, Chromosome, Nucleus, Cell
I have a flower that is Red and one that is White. They make a pink baby. is this an example of Codominance? Why?
It is not because it is a MIX and not both showing up
How many steps are in Mitosis and what are they named?
6
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
PCR works by heating up DNA to break up this
What is hydrogen bonds
What is gene Therapy, is it commonly used (why) and what are its pros?
The technique used to cure heritable diseases by replacing mutant genes with good genes; to treat or prevent diseases
It is uncommon due to it difficult getting the working gene into the specific cells where it is needed
can reduce disease causing proteins, increasing working proteins, or even produce new proteins
