About the App
IRAKU is an educational app for learning genetics, DNA and evolution through moving simulations. Its modes are grouped into four categories — DNA & Gene Expression (DNA Double Helix, Central Dogma, Codon Translator), How Inheritance Works (Mendelian Cross, Meiosis & Crossing Over, Karyotype), Populations & Evolution (Mutation & Evolution, Hardy-Weinberg, Phylogenetic Tree) and Biotechnology (PCR Amplification, CRISPR Lab). Every mode unfolds in 4 steps and ends with a real example from research or observation.
