Reação em cadeia da polimerase (PCR) - Khan Academy
A reação em cadeia da polimerase, ou PCR, é uma técnica para fazer muitas cópias de uma região específica do DNA, in vitro (em um tubo de ensaio, ao invés de um organismo). A PCR depende de uma DNA polimerase termoestável, a Taq polimerase, e requer primers de DNA projetados especificamente para a região de interesse do DNA .
