Interactive exploration

Cells, Life & EvolutionViruses, bacteriophages and host-dependent replication

How does a virus make copies without its own cell?

Open a real MS2 reconstruction, follow its RNA, and test what happens when a needed step is missing. Discover whose instructions, tools and materials make new particles possible.

Interactive exploration

Cells, Life & EvolutionNatural selection, evolution, peppered moths and genetic drift

How can a population change over generations?

Meet two real peppered-moth forms. Follow survivors, trace inherited copies into offspring, and replay a population under different conditions. Compare the teaching model with what researchers actually measured.

Interactive exploration

Cells, Life & EvolutionInheritance, genes, chromosomes and why siblings look different

How do genes pass from parents to offspring?

Inspect a real fruit fly reconstruction, choose inherited copies, exchange chromosome segments and test why a probability does not promise an exact family. Follow linked markers from parent to gamete to offspring.

Cells, Life & EvolutionGut microbes, the microbiome and dietary fiber

What happens to the food your own enzymes cannot digest?

Match two kinds of fiber to the microbes that can use them. Look through a bacterial surface, inspect a real enzyme holding a sugar chain, and sort the different kinds of products that microbes can make.

Cells, Life & EvolutionDNA, genes and proteins

How does DNA help a cell build a protein?

Take apart a human ribosome, follow a message three letters at a time, then change a DNA base and discover what the peptide does.

Cells, Life & EvolutionPhotosynthesis and plant growth

Where does a plant get the material to grow?

Open a leaf, explore a chloroplast, and supply a tiny carbon-building recipe. Discover what comes from air, what comes from water, and what light contributes.
