What do genes do?
Genes: Information
What are genes information for?
information for making proteins that have different functions in cells
Key Principles: Pillars of Genetics
Mutagenesis
mutations in DNA result can result in loss of gene function and this leads to a change in phenotype of the cell/organism
Complementation
adding a normal gene to an organism that already has a broken gene, and this restores the normal phenotype.
Segregation
meiosis determines HOW nuclear genes get passed on to progeny
Linkage
genes that are close together on a chromo tend to be inherited together
Phenotype
Case Studies
1) Girl with defective striated muscle
2) arctic apples and potatoes
enzyme (polyphenol oxidase) is silenced
