Guida verificata passo dopo passo1
Understand the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein.
Identify the process of transcription, where the information in DNA is copied into messenger RNA (mRNA).
Recall that transcription requires an enzyme that can synthesize RNA using a DNA template.
Recognize that DNA polymerase synthesizes DNA, not RNA, so it is not involved in mRNA synthesis.
Conclude that RNA polymerase (specifically RNA polymerase II in eukaryotes) is the enzyme responsible for synthesizing mRNA from the DNA template during transcription.
