Study Notes
Biology Exam Prep: Key Concepts and Details
- Phase-contrast microscopy is better for live cells, while it does not provide the resolution for virus internal structure.
- Certain viruses, such as HPV and hepatitis B and C viruses, are known to be direct causes of specific types of cancer.
- Subcellular fractionation allows researchers to analyze the biochemical properties of different cell organelles.
- Model organisms like C. elegans and Drosophila are primarily used to understand fundamental biological processes.
- E. coli is primarily used in genetic research due to its fast growth rate and simple genetics.
- HeLa cells are immortal, meaning they can divide indefinitely in culture, making them useful in research.
- Fluorescence Resonance Energy Transfer (FRET) is primarily used to measure the distance between two molecules within cells.
- Arabidopsis thaliana is a popular model organism in plant biology due to its small genome and short life cycle.
- Viruses are not mainly used as a treatment for cancer, and most cancer drugs were not developed directly from virus research.
- Subcellular fractionation does not involve magnification and is not used for genetic sequencing.
- Model organisms like C. elegans and Drosophila are not primarily used for testing pharmaceutical drugs or to produce antibodies for research.
- E. coli does not have a large and complex genome, its genetic material is not similar to that of humans, and it does not produce human-like proteins.
