Biology 1AL – Lecture 4: Complementation I, Genetics and Molecular Biology
 |
| Complementation I, Genetics and Molecular Biology |
This lecture introduces the molecular foundations of genetics through practical laboratory techniques. Students explore Polymerase Chain Reaction (PCR) as a method for amplifying DNA, followed by complementation tests that reveal how genes interact to produce phenotypes. The session connects these experiments to broader cellular processes — mitosis and meiosis — emphasizing how genetic variation arises and is maintained.
The reading list from the lab manual and Campbell Biology chapters guides students through the theoretical background of DNA replication, chromosomal behavior, and sequencing methods. Together, these topics form the bridge between classical genetics and modern molecular biology.
This lecture stands out for its integration of hands‑on experimentation with conceptual understanding, showing how molecular tools illuminate the invisible architecture of heredity. It’s a cornerstone for anyone studying the transition from genotype to phenotype in living systems.
