2 Aplikace: teorie biotechnologie farmacie medicína genetické inženýrství Informatika nad biologickými molekulami (daty). Bioinformatika extrahuje molekulární informační systém pro molekulární biologii. Bioinformatika je konceptualizovaná molekulární biologie (ve smyslu fyzikálně chemickém) na níž je aplikována informatika (odvozená od matematické informatiky a statistiky). bioinformatika
