Transcriptional Regulation by Mediator Complex Gene Regulation Alterations in the regulation of gene expression are frequently associated with developmental diseases or cancer. Transcription activation is a key phenomenon in the regulation of gene expression. In all eukaryotes mediator of RNA polymerase II transcription (Mediator) a large complex with modular organization is generally required for transcription by RNA polymerase II and it regulates various steps of this process. The main…

The lifespans of flies and worms are prolonged by limiting the activity of an enzyme common to all animals, finds a UCL-led study. The enzyme – RNA polymerase III (Pol III) – is present in most cells across all animal species, including humans. While it is known to be essential for making pro...
Transcription proceeds in the following general steps: One or more sigma factor protein binds to the RNA polymerase holoenzyme, allowing it to bind to promoter DNA. RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. This is done by breaking the hydrogen bonds between complementary DNA nucleotides. RNA polymerase adds matching RNA nucleotides to the complementary nucleotides of one DNA strand.

DNA is transcribed by the enzyme RNA polymerase. The RNA polymerase (pale blue) moves stepwise along the DNA, unwinding the DNA helix at its active site. As it progresses, the polymerase adds nucleotides (here, small “T” shapes) one
