Does Transcription Require Energy?

One advantage involves the energy required for transcription and translation; specifically, the energy needed to drive the process of transcription could be provided by the large-scale expenditure of unstable nucleotide triphosphates during the process of translation.

Is ATP needed for transcription?

The synthesis of 250-330 nucleotide run-off transcripts and 4-9 nucleotide Sarkosyl-resistant transcription intermediates requires ATP both for RNA synthesis and for activation of the system prior to RNA synthesis. ... Thus we argue that ATP activates the transcription system in a step prior to RNA synthesis.

Does translation require energy?

The energy required for translation of proteins is significant. For a protein containing n amino acids, the number of high-energy phosphate bonds required to translate it is 4n-1. ... The correct amino acid is covalently bonded to the correct transfer RNA (tRNA) by amino acyl transferases.
