Bacterial Genetics Lab - No smiling in the lab! 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 Transformation Lab - Ecoli is so much fun! 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 plate their Ecoli cells for overnight incubation Bacterial Transformation Lab - The students plate their Ecoli cells on varying media Bacterial Transformation Lab - Travis adds a plasmid with the GFP gene to the students' Ecoli cells DNA Fingerprinting Lab - Collecting cheek cell DNA! DNA Fingerprinting Lab - Deanne explains how the students are going to use PCR to amplify a particular VNTR locus DNA Fingerprinting Lab - The students add chelex beads to their cells to avoid DNA degradation DNA Fingerprinting Lab - The students centrifuge their samples to pellet any cellular debris 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 Q&A - At the end of the day, the students answer questions about the labs for candy prizes Replica Plating Lab - Don't breathe on the agar! Replica Plating Lab - Gridding bacterial colonies! Replica Plating Lab - The students hard at work! Replica Plating Lab - The students pick bacterial colonies and transfer them to nutrient agar plates Yeast Sunscreen Lab - A student's results show that wildtype yeast can fix mutations caused by UV rays (growth), while mutant yeast cannot (no growth) Yeast Sunscreen Lab - It appears that the SPF of sunscreen is not too important Yeast Sunscreen Lab - These results show that aluminum foil, sunscreen, and fabric all protect against UV rays
