Description

This interactive, modular lab explores the techniques used to identify different types of bacteria based on their DNA sequences.

In this lab, students prepare and analyze a virtual bacterial DNA sample. In the process, they learn about several common molecular biology methods, including DNA extraction, PCR, gel electrophoresis, and DNA sequencing and analysis. These methods are applicable in a wide variety of settings, including scientific research and forensic labs.

The lab contains an interactive lab space and an informational notebook with detailed procedures. It also includes supplementary resources, such as a glossary of scientific terms, images of equipment and tools, and an encyclopedia of bacteria.

The accompanying worksheet provides structure and guidance as students perform the procedures in the lab.
