Bacterial Genetics Lab - The students investigate how much bacteria is on the elevator Bacterial Genetics Lab - The students lick the nutrient agar plates to see what will grow Bacterial Genetics Lab - The students make designs on MacConkey's media Bacterial Genetics Lab - The students use lac+ and lac- bacteria, allowing for pink and white colonies to grow Bacterial Genetics Lab - These girls are such trouble! Bacterial Transformation Lab - Ecoli is so much fun! Bacterial Transformation Lab - Hard at work! Bacterial Transformation Lab - Spread those Ecoli cells! Bacterial Transformation Lab - The students add Luria Recovery Broth to their Ecoli cells after the heat shock treatment Bacterial Transformation Lab - The students add chloride salts to their Ecoli cells (to induce competency) Bacterial Transformation Lab - The students answer questions about the GFP Transformation Lab Bacterial Transformation Lab - The students plate their Ecoli cells for overnight incubation Bacterial Transformation Lab - The students plate their Ecoli cells on varying media Bacterial Transformation Lab - Travis comes around to add a plasmid with the GFP gene to the students' Ecoli cells DNA Fingerprinting Lab - After decanting the supernatant, the students resuspend their cells DNA Fingerprinting Lab - Collecting cheek cell DNA! DNA Fingerprinting Lab - The students add chelex beads to their cells to avoid DNA degradation DNA Fingerprinting Lab - The students prepare their DNA samples for the PCR reaction DNA Fingerprinting Lab - The students put their DNA samples into a heating block for ten minutes DNA Fingerprinting Lab - The students use a toothpick to obtain their cheek cell DNA Model Organism Lab - A microscopic view of zebrafish embryos at a later stage of development Replica Plating Lab - Gridding bacterial colonies! Replica Plating Lab - The students pick bacterial colonies and transfer them to nutrient agar plates
