Studying DNA and RNA
Real-Time RT-PCR for Gene Expression Tracking
Description
Real-time RT-PCR tracks gene expression by measuring how much target DNA is made during PCR. It starts with mRNA, which is converted into complementary DNA, or cDNA, by an enzyme called reverse transcriptase. The cDNA is then amplified by PCR so the target sequence can be measured.

Transcript
A reação em cadeia da polimerase com transcrição reversa em tempo real, ou RT-PCR em tempo real, pode quantificar um RNA de interesse à medida que a reação progride.
Para começar, a transcriptase reversa copia o RNA em complementar, ou cDNA. A RNase H digere o RNA original, deixando para trás pequenos primers ligados ao cDNA.
Uma f...
