IRAKU
From the DNA double helix to population genetics and CRISPR — IRAKU lets you see and play with the molecular mechanics of inheritance on iOS and Android.
Simulators
DNA Double Helix
Pseudo-3D rotating helix. Enter a sequence, randomize, or mutate single bases. Tap any base for details.
Central Dogma
DNA to mRNA to protein. Transcription and translation rendered as a five-stage animation.
Punnett Square
Pick parental genotypes; see the offspring distribution. Switch to dihybrid for the 9:3:3:1 ratio.
Codon Translator
DNA to mRNA to amino acids, with three reading frames and a built-in 64-codon table.
Mutation & Evolution
Apply mutation and selection to a population. Watch genotype frequencies shift across generations.
Hardy-Weinberg
p² + 2pq + q². Slide allele frequency and fitness to watch the equilibrium drift.
Phylogenetic Tree
Compute Hamming distances between sequences and cluster via UPGMA to draw a tree.
CRISPR Lab
Design a guide RNA, cut with Cas9, and inspect NHEJ or HDR repair outcomes.
Karyotype Viewer
The 23 chromosome pairs. Tap to switch among normal, trisomies, and sex-chromosome aneuploidies.
