The Big Question
How do we explore the unseen microbial worlds that shape our planet, and what tools help us discover their secrets?
💡 Did You Know?
Metagenomics allows scientists to explore the diversity and function of microbial communities in their natural habitats.
MetagenomicsThe study of genetic material recovered directly from environmental samples, bypassing the need for lab cultivation of individual species.
COURSE OVERVIEW
Get ready to embark on an exciting journey into the hidden world of microbes. This mini-course will guide you through the complete process of metagenomic analysis, from initial sample collection to extracting biological insights. Here’s a glimpse of the 11 lessons awaiting you:
- Lesson 1 Welcome to Metagenomics: Discovering the Invisible World
- Lesson 2 Lab Foundations: Metric System, Volume, Weight, and Pipetting
- Lesson 3 DNA and Genomic DNA: The Code Behind the Sample
- Lesson 4 Site Selection and Field Sampling
- Lesson 5 DNA Extraction from Soil
- Lesson 6 DNA Quantitation and Nanodrop Analysis
- Lesson 7 PCR: Testing DNA Purity
- Lesson 8 Agarose Gel Electrophoresis
- Lesson 9 Oxford Nanopore Library Prep
- Lesson 10 Adapter Ligation, Quantification & Sequencing
- Lesson 11 Bioinformatics
Metagenomics is revolutionizing fields from medicine to environmental science. Imagine discovering new antibiotics in soil, understanding gut microbiome health, or tracking pollution sources – all by analyzing DNA directly from the environment.

What does metagenomics sequence from an environmental sample?
2 · True / False — Myth or Fact?
Myth or Fact?
Metagenomics requires culturing each microbe in the lab before its DNA can be sequenced.
Myth — metagenomics reads DNA straight from the sample, capturing the >99% of microbes that resist lab culture.
3 · Fill-in-the-Blank
Fill in the blank
Metagenomics studies genetic material recovered directly from samples, including organisms that cannot be in a lab.
4 · Predict & Reveal
Make a prediction
Roughly what fraction of environmental microbes can be grown in standard lab culture?
Less than 1% — the “great plate count anomaly,” and exactly why culture-independent metagenomics opened up the microbial world.
