Course Objectives

Learning Outcomes

Upon successful completion of this course, students will be able to:

• Demonstrate scientific literacy by articulating and practicing the scientific method.

• Evaluate data for validity and reliability.

• Interpret scientific data from a variety of sources.

• Identify major macromolecules and their importance to living organisms.

• Explain metabolism and its role in cellular processes.

• Compare and contrast prokaryotic and eukaryotic structures and processes of cell division and replication.

• Explain gene expression and solve problems in transmission genetics.

Key Topics and Concepts

Molecular Biology

Molecular biology focuses on the structure and function of the molecules essential for life, such as DNA, RNA, and proteins.

• DNA & RNA: Nucleic acids that store and transmit genetic information.

• Proteins: Macromolecules that perform a variety of cellular functions.

• Central Dogma: The flow of genetic information from DNA to RNA to protein.

Example: DNA replication and transcription are key molecular processes in all living cells.

Cellular Biology

Cellular biology examines the structure, function, and processes of cells, the basic units of life.

• Cell Types: Prokaryotic (no nucleus) vs. Eukaryotic (nucleus present).

• Cell Division: Mitosis (somatic cells) and Meiosis (gametes).

• Cellular Organelles: Nucleus, mitochondria, ribosomes, etc.

Example: Mitosis ensures equal distribution of genetic material to daughter cells.

Genetics

Genetics is the study of heredity and variation in organisms.

• Gene Expression: The process by which information from a gene is used to synthesize a functional gene product.

• Transmission Genetics: Patterns of inheritance (Mendelian genetics).

• Genotype vs. Phenotype: Genetic makeup vs. observable traits.

Example: Mendel's laws describe how traits are inherited through generations.

Metabolism

Metabolism encompasses all chemical reactions that occur within living organisms to maintain life.

• Anabolism: Building up complex molecules from simpler ones.

• Catabolism: Breaking down complex molecules to release energy.

• ATP: The primary energy currency of the cell.

Example: Cellular respiration converts glucose into ATP.

Formula:

Cell Division and Replication

Cell division is essential for growth, development, and reproduction. Replication ensures genetic continuity.

• Mitosis: Produces two identical daughter cells.

• Meiosis: Produces four genetically diverse gametes.

• DNA Replication: Semi-conservative process ensuring each new cell receives a complete set of DNA.

Example: Meiosis increases genetic diversity through recombination and independent assortment.
