The set covers the figures a molecular and cell biology course asks you to label: DNA and how it is copied and read, how a cell divides, and the cycles that move energy through a cell. Each page is one drawing with a number on every part.

More about these tools

A number lights up and you choose or type what belongs there, or you get a name and tap its place. Study shows every answer with a line on what it does, and missed ones come back when the round ends.

Use a page before a unit quiz to find the names you do not know, or print the blank copy and its key for a class. The first page is the citric acid cycle: nine molecules, eight enzymes and seven points where something leaves. Names and steps were checked against an open college biology textbook on the date each page shows.
