A rectangular green algal cell under a microscope, filled with chloroplasts.

Concepts
The cell is a living landscape
A membrane, a set of compartments, and a supply of energy. The picture is a place you can walk through, not a factory floor.

A brass and glass sculpture of a DNA double helix on a dark bench.

Discoveries
How the helix was read
Photo 51, the model, and the names that belong on the page with it.

White flowers and a green pod on a garden pea plant.

Experiments
A garden that settled inheritance
Pea crosses, swan-neck flasks, and the density shift that showed how DNA is copied.

A pale jellyfish suspended in black water.

Serendipity
A glow nobody ordered
A contaminated plate, a hot-spring enzyme, and the jellyfish protein that became a lamp.

India
The harvest, and its cost
Khorana, Ramachandran, Janaki Ammal, and the wheat yields that also had an ecological bill.

Branching coral and small orange fish under shafts of sunlight.

World
The work, with the names attached
Franklin’s fibre pattern, Tu Youyou’s artemisinin, and the collaborators a short version usually drops.

Look inside the cell

Choose a part, or watch the two strands come apart to be copied. Each new double helix keeps one old strand.

The plasma membrane is a lipid bilayer with proteins. It keeps the cell’s chemistry in and lets chosen molecules through. It is a working boundary, not a wall.
