Biotechnology harnesses cellular and molecular processes to develop technologies and products that improve human health, agriculture, and industry. From the polymerase chain reaction that revolutionized forensics to CRISPR-Cas9 gene editing that promises cures for genetic diseases, biotech tools are reshaping what is possible in medicine and beyond.

These simulations let you amplify DNA through PCR thermal cycling, design CRISPR guide RNAs and predict editing outcomes, separate DNA fragments by electrophoresis, optimize bioreactor growth conditions, and model gene expression with promoter-driven transcription — all with accurate biochemical models and real-time animated visualizations.
