Study Notes
Concordance Rates and Disease
- A concordance rate of 75% for MZ twins and 30% for DZ twins indicates a significant genetic component to the disease.
Protein Synthesis
- Ribosomes use RNA to synthesize proteins.
Epigenetics Examples
- Sperm protamine interaction with DNA is an example of epigenetics.
Phenotype Example
- Hair color is an example of a phenotype.
Cell Size Determination
- Cell size is NOT determined by the amount of cytosol, DNA in the nucleus, or translation of DNA.
DNA Location
- DNA is stored in the nucleus of a cell.
Genetic Mutation Triggers
- Genetic mutations occur due to chance.
RNA vs DNA Bases
- Uracil is an RNA nitrogenous base, but not a DNA base.
DNA Repair During Replication
- Proofreading is a process that repairs DNA strands during replication.
Heritable vs. Non-Heritable Mutations
- Mutations in somatic cells are not passed down to offspring.
