GeneLab: the free DNA and molecular-biology game for teens

GeneLab builds molecular biology from the ground up, one level at a time. Learners go from the atoms of life through nucleotides, base pairing, transcription, and translation, all the way to protein structure and a single-letter mutation that causes sickle-cell. Aimed at middle and high school, it's free, with no ads and no tracking of your kids.

What kids learn

How it works

Each level is a sequence of multiple-choice steps: an instruction appears, kids tap the right answer, and a teaching note explains it. Answering in order animates a stage visual — a nucleotide assembling, a strand filling in, a peptide chain growing — so the quiz feels like building the molecule. Stars reflect the share of first-try correct answers.

A grown-up signs in once and adds a player for each kid, so GeneLab's stars and progress save to your account and follow you to any device.
