  2. Bacterial transcription - Wikipedia

    en.wikipedia.org/wiki/Bacterial_transcription

    Bacterial transcription differs from eukaryotic transcription in several ways. In bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm. [14]

  3. Transcription (biology) - Wikipedia

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

    Regulation of transcription in mammals. An active enhancer regulatory region of DNA is enabled to interact with the promoter DNA region of its target gene by the formation of a chromosome loop. This can initiate messenger RNA (mRNA) synthesis by RNA polymerase II (RNAP II) bound to the promoter at the transcription start site of the gene. The ...

  5. Ribosome-binding site - Wikipedia

    en.wikipedia.org/wiki/Ribosome-binding_site

    Prokaryotic ribosomes begin translation of the mRNA transcript while DNA is still being transcribed. Thus translation and transcription are parallel processes. Bacterial mRNA are usually polycistronic and contain multiple ribosome binding sites. Translation initiation is the most highly regulated step of protein synthesis in prokaryotes. [5]

  6. 5′ flanking region - Wikipedia

    en.wikipedia.org/wiki/5′_flanking_region

    Prokaryotes only have three promoter elements: two elements are present -35 and -10 nucleotides upstream of the transcription start site, and the third is directly upstream the transcription start site. Prokaryotic promoter elements are not identical among species, but have a consensus sequence of 6 nucleotides each.

  7. Activator (genetics) - Wikipedia

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

    [2] [3] If the regulatory sequence is located far away, the DNA will loop over itself (DNA looping) in order for the bound activator to interact with the transcription machinery at the promoter site. [2] [3] In prokaryotes, multiple genes can be transcribed together , and are thus controlled under the same regulatory sequence. [2]

  8. Five prime untranslated region - Wikipedia

    en.wikipedia.org/wiki/Five_prime_untranslated_region

    The 5′ UTR begins at the transcription start site and ends one nucleotide (nt) before the initiation sequence (usually AUG) of the coding region. In prokaryotes, the length of the 5′ UTR tends to be 3–10 nucleotides long, while in eukaryotes it tends to be anywhere from 100 to several thousand nucleotides long. [4]

  9. Rho factor - Wikipedia

    en.wikipedia.org/wiki/Rho_factor

    A Rho factor acts on an RNA substrate. Rho's key function is its helicase activity, for which energy is provided by an RNA-dependent ATP hydrolysis. The initial binding site for Rho is an extended (~70 nucleotides, sometimes 80–100 nucleotides) single-stranded region, rich in cytosine and poor in guanine, called the rho utilisation site (rut), in the RNA being synthesised, upstream of the ...
