WebAug 23, 2024 · DNA transcription, also known as RNA synthesis is the process by which genetic information that is contained in DNA is re-written into messenger RNA (mRNA) by an RNA polymerase enzyme. The synthesized mRNA is transported out of the cell nucleus where it will later on aid in the synthesis of proteins by the mechanism of translation.

However, deletion of Rpb4 or Spt4 in rad26Δ cells restores TCR in the RPB2 and URA3 genes (21,22). These studies indicate that TCR is more repressed in the slowly transcribed genes in the absence of Rad26.
