Study Notes
Animal Cell Architecture
- Diagram of an animal cell, highlighting key components:
- Nucleus (contains chromatin/DNA and nucleolus)
- Cytoplasm (includes cytosol, ribosomes, Golgi apparatus, endoplasmic reticulum, mitochondria, lysosomes, peroxisomes, microtubules, actin filaments, intermediate filaments, and vesicles)
- Plasma membrane (external boundary)
- Centrosome (contains centrioles)
- Extracellular matrix (surrounding the cell)
Model Organisms in Biological Research
-
Drosophila melanogaster (Fruit Fly)
- Serves as a model organism for studying human development and the genetic basis of human diseases.
-
Caenorhabditis elegans (Nematode Worm)
- Relatively simple, with a defined number of body cells (959).
- Provides a controlled system for studying cell division, movement, and specialization.
- Useful for studying apoptosis (programmed cell death) and its relevance to cancer development.
-
Zebrafish
- Transparent embryos facilitate observation of cell behavior during development.
- Valuable model for vertebrate development.
-
Mouse
- Well-established model organism for mammalian genetics, development, immunology, and cell biology.
- Allows for the study of engineered mutations and gene insertions.
Molecular Forces in Protein Folding
- Hydrophobic interactions play a crucial role in protein folding.
- Nonpolar (hydrophobic) amino acids cluster inside the folded protein, minimizing contact with water.
- Polar amino acids tend to be positioned on the protein's surface, allowing them to interact with water and other polar molecules.
- When polar amino acids are located inside the protein, they often form hydrogen bonds with other polar amino acids or the polypeptide backbone.
