What role do transcription factors, histones, acetylation and methylation sites play in gene expression? Title: What role do transcription factors, histones, acetylation and methylation sites play in gene expression? Post by: rk90 on Sep 14, 2012 Transcription is the first step leading to gene expression. The stretch of DNA transcribed into an RNA molecule is called a transcription unit and encodes at least one gene. If the gene transcribed encodes a protein, the result of transcription is messenger RNA (mRNA), which will then be used to create that protein via the process of translation. Alternatively, the transcribed gene may encode for either ribosomal RNA (rRNA) or transfer RNA (tRNA), other components of the protein-assembly process, or other ribozymes.
