Virtual Mol-Bio Lab
Description
The Virtual Mol-Bio Lab is an interactive, browser-based simulation that walks learners through a complete molecular biology workflow — from DNA/RNA extraction through cDNA synthesis, primer design, PCR setup, and agarose gel electrophoresis — without needing access to a physical lab. Rather than passively reading about each technique, learners drag reagents into tubes, build their own PCR programs, run live calculators to determine primer concentrations and dilutions, and watch simulated gel bands migrate under UV light, all using the same logic, volumes, and equations a real bench scientist would use. Built-in quizzes at the end of each stage reinforce key concepts, making it suitable for students, early-career researchers, or anyone who wants hands-on intuition for molecular biology techniques before ever touching a pipette.
Learning Outcomes
By completing this lab, learners will be able to: Explain the general logic behind DNA and RNA extraction from different sample types and describe the reverse transcription reaction that converts RNA into cDNA. Design PCR primers for a target gene and calculate their resuspension volume, working dilution, and annealing temperature from basic mass, concentration, and sequence data. Assemble a complete PCR reaction mix and construct a thermal cycler program (denaturation, annealing, extension, cycle number, and final extension). Prepare an agarose gel at a given percentage, run an electrophoresis experiment, and interpret band size and quality using a DNA ladder under UV visualization. Connect each step to the next in a real molecular biology workflow, understanding why each reagent, temperature, and calculation matters rather than memorizing fixed values.
