Assessment and Grading

Key Concepts and Definitions

Scientific Method

• Definition: A systematic approach to inquiry involving observation, hypothesis formation, experimentation, and analysis.

• Steps:

  1. Observation

  2. Question

  3. Hypothesis

  4. Experiment

  5. Data Collection

  6. Analysis

  7. Conclusion

• Application: Used in both lecture and laboratory investigations to design and interpret experiments.

Basic Chemistry for Biology

• Atoms: The smallest unit of an element, composed of protons, neutrons, and electrons.

• Bonds: Chemical connections between atoms (ionic, covalent, hydrogen bonds).

• Water: Essential for life; properties include cohesion, adhesion, high specific heat, and solvent abilities.

• pH: Measure of hydrogen ion concentration; important for cellular processes. Equation:

Biological Macromolecules

• Carbohydrates: Sugars and starches; energy storage and structural roles.

• Lipids: Fats, oils, phospholipids, steroids; energy storage, membrane structure.

• Proteins: Composed of amino acids; function as enzymes, structural components, signaling molecules.

• Nucleic Acids: DNA and RNA; store and transmit genetic information.

Cell Structure and Function

• Prokaryotic Cells: Lack a nucleus; include bacteria and archaea.

• Eukaryotic Cells: Have a nucleus and membrane-bound organelles; include plants, animals, fungi, protists.

• Major Organelles: Nucleus, mitochondria, chloroplasts, endoplasmic reticulum, Golgi apparatus, lysosomes.

Cell Membrane and Transport

• Plasma Membrane: Phospholipid bilayer with embedded proteins; regulates entry and exit of substances.

• Transport Mechanisms:

  • Simple diffusion

  • Facilitated diffusion

  • Active transport

  • Osmosis

Cellular Energy and Metabolism

• Metabolism: All chemical reactions in a cell.

• Cellular Respiration: Process of converting glucose and oxygen into ATP, water, and carbon dioxide. Equation:

• Fermentation: Anaerobic process to generate energy when oxygen is absent.

• Enzymes: Biological catalysts that speed up reactions by lowering activation energy.

Cell Division and Genetics

• Mitosis: Division of a cell into two genetically identical daughter cells.

• Meiosis: Division producing gametes with half the chromosome number, increasing genetic diversity.

• Mendelian Genetics: Principles of inheritance based on segregation and independent assortment.

• Chromosomal Basis of Inheritance: Genes are located on chromosomes, which segregate during meiosis.

Molecular Biology of the Gene

• DNA Structure: Double helix composed of nucleotides (A, T, C, G).

• Central Dogma: Flow of genetic information from DNA to RNA to protein. DNA RNA $\rightarrow$ Protein

• DNA Replication: Semi-conservative process ensuring genetic continuity.

Expectations and Success Strategies

• Attend all lectures and labs; participation is essential.

• Complete readings and assignments before class.

• Use MasteringBiology and Blackboard for assignments, quizzes, and resources.

• Plan for 10-15 hours per week of study and homework outside of class.

• Seek help from the instructor, tutoring center, or classmates as needed.

Academic Policies and Support

• Academic Honesty: All work must be original; plagiarism and cheating result in disciplinary action.

• Accessibility: Accommodations available for students with disabilities; contact Student Accessibility Services.

• Veteran Services: Support available for veterans through the Veteran Affairs Office.

• Diversity, Equity, and Inclusion: The course values and supports all student identities and backgrounds.
