  2. RNA polymerase - Wikipedia

    en.wikipedia.org/wiki/RNA_polymerase

    Structure of eukaryotic RNA polymerase II (light blue) in complex with α-amanitin (red), a strong poison found in death cap mushrooms that targets this vital enzyme Eukaryotes have multiple types of nuclear RNAP, each responsible for synthesis of a distinct subset of RNA.

  3. Eukaryotic transcription - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_transcription

    Unlike prokaryotic RNA polymerase that initiates the transcription of all different types of RNA, RNA polymerase in eukaryotes (including humans) comes in three variations, each translating a different type of gene. A eukaryotic cell has a nucleus that separates the processes of transcription and translation.

  4. RNA polymerase II - Wikipedia

    en.wikipedia.org/wiki/RNA_polymerase_II

    RNA polymerase II holoenzyme is a form of eukaryotic RNA polymerase II that is recruited to the promoters of protein-coding genes in living cells. [11] It consists of RNA polymerase II, a subset of general transcription factors , and regulatory proteins known as SRB proteins.

  5. Transcription (biology) - Wikipedia

    en.wikipedia.org/wiki/Transcription_(biology)

    In archaea and eukaryotes, RNA polymerase contains subunits homologous to each of the five RNA polymerase subunits in bacteria and also contains additional subunits. In archaea and eukaryotes, the functions of the bacterial general transcription factor sigma are performed by multiple general transcription factors that work together. [ 6 ]

  6. Transcriptional regulation - Wikipedia

    en.wikipedia.org/wiki/Transcriptional_regulation

    This allows the RNA polymerase to bind to the mal promoter (#3). Transcription of malE, malF, and malG genes then proceeds (#4) as maltose activator protein and RNA polymerase moves down the DNA. [1] malE encodes for maltose-binding periplasmic protein and helps maltose transport across the cell membrane.

  7. RNA polymerase II holoenzyme - Wikipedia

    en.wikipedia.org/wiki/RNA_polymerase_II_holoenzyme

    RNA polymerase II holoenzyme is a form of eukaryotic RNA polymerase II that is recruited to the promoters of protein-coding genes in living cells. [ 1 ] [ 2 ] It consists of RNA polymerase II , a subset of general transcription factors , and regulatory proteins known as SRB proteins [ clarification needed ] .

  8. Activator (genetics) - Wikipedia

    en.wikipedia.org/wiki/Activator_(genetics)

    Activator interactions with RNA polymerase are mostly direct in prokaryotes and indirect in eukaryotes. [2] In prokaryotes, activators tend to make contact with the RNA polymerase directly in order to help bind it to the promoter. [ 2 ]

  9. RNA polymerase I - Wikipedia

    en.wikipedia.org/wiki/RNA_polymerase_I

    RNA polymerase 1 (also known as Pol I) is, in higher eukaryotes, the polymerase that only transcribes ribosomal RNA (but not 5S rRNA, which is synthesized by RNA polymerase III), a type of RNA that accounts for over 50% of the total RNA synthesized in a cell.
