How to separate rna from dna
WebIn the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. WebFirst, double-stranded template DNA containing the target sequence is denatured at approximately 95 °C. The high temperature required to physically (rather than enzymatically) separate the DNA strands is the reason the heat-stable DNA polymerase is required. Next, the temperature is lowered to approximately 50 °C.
