DNA replication requires RNA primers while transcription does not
Is it true that DNA replication requires RNA primers while transcription does not?
Yes. DNA replication strictly requires RNA primers to provide a free 3'-OH group for chain elongation, whereas RNA polymerases (transcription) are capable of initiating de novo synthesis without a primer.
Verdict: SUPPORTED · 2 sources for, 0 against · Last checked
The retrieved papers and established molecular biology principles confirm that DNA replication relies on RNA primers to initiate synthesis because DNA polymerases cannot start chains de novo. In contrast, RNA polymerases (transcription) initiate synthesis de novo using incoming nucleoside triphosphates without needing a pre-existing primer. Thus, the claim is well-supported by fundamental biological principles and corroborated by the mechanism of transcription initiation.
