Study Notes
Cell Biology
Cell Structure
- Plasma membrane: phospholipid bilayer that separates cell from environment
- Cytoplasm: jelly-like substance inside cell where metabolic reactions occur
- Nucleus: membrane-bound organelle that contains DNA
- Mitochondria: organelles responsible for cellular respiration and energy production
- Ribosomes: site of protein synthesis
- Lysosomes: membrane-bound organelles that contain digestive enzymes
- Golgi apparatus: involved in protein modification and secretion
- Cytoskeleton: network of filaments that provides structural support and shape
Cellular Processes
- Photosynthesis: process by which plants convert light energy into chemical energy
- Cellular respiration: process by which cells generate energy from glucose
- Mitosis: process of cell division that results in two identical daughter cells
- Meiosis: process of cell division that results in four non-identical daughter cells (gametes)
Genetics
Mendelian Genetics
- Laws of Inheritance:
- Law of Segregation: alleles separate during gamete formation
- Law of Independent Assortment: alleles for different traits are sorted independently
- Law of Dominance: dominant alleles are expressed over recessive alleles
- Punnett Squares: graphical representation of probability of genotypes and phenotypes
DNA Structure and Function
- Double helix model: two complementary strands of nucleotides that twist together
- Nucleotides: building blocks of DNA that consist of sugar, phosphate, and nitrogenous base
- Genetic code: sequence of nucleotides that determines amino acid sequence
- Replication: process of creating an exact copy of DNA
- Transcription: process of creating RNA from DNA template
- Translation: process of creating protein from RNA sequence
Gene Expression and Regulation
- Gene expression: process of converting genetic information into functional product
- Gene regulation: mechanisms that control gene expression
- Epigenetics: study of heritable changes in gene expression that do not involve DNA sequence changes
