  2. Bacterial transcription - Wikipedia

    en.wikipedia.org/wiki/Bacterial_transcription

    In fact, many prokaryotic genes occur in operons, which are a series of genes that work together to code for the same protein or gene product and are controlled by a single promoter. [2] Bacterial RNA polymerase is made up of four subunits and when a fifth subunit attaches, called the sigma factor (σ-factor), the polymerase can recognize ...

  3. Transcription (biology) - Wikipedia

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

    This is called abortive initiation, and is common for both eukaryotes and prokaryotes. [37] Abortive initiation continues to occur until an RNA product of a threshold length of approximately 10 nucleotides is synthesized, at which point promoter escape occurs and a transcription elongation complex is formed. [citation needed]

  4. Abortive initiation - Wikipedia

    en.wikipedia.org/wiki/Abortive_initiation

    Abortive initiation is a normal process of transcription and occurs both in vitro and in vivo. [2] After each nucleotide-addition step in initial transcription, RNA polymerase, stochastically, can proceed on the pathway toward promoter escape (productive initiation) or can release the RNA product and revert to the RNA polymerase-promoter open complex (abortive initiation).

  5. Bacterial translation - Wikipedia

    en.wikipedia.org/wiki/Bacterial_translation

    Initiation of translation in bacteria involves the assembly of the components of the translation system, which are: the two ribosomal subunits (50S and 30S subunits); the mature mRNA to be translated; the tRNA charged with N-formylmethionine (the first amino acid in the nascent peptide); guanosine triphosphate (GTP) as a source of energy, and the three prokaryotic initiation factors IF1, IF2 ...

  7. Translation (biology) - Wikipedia

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

    In prokaryotes (bacteria and archaea), translation occurs in the cytosol, where the large and small subunits of the ribosome bind to the mRNA. In eukaryotes , translation occurs in the cytoplasm or across the membrane of the endoplasmic reticulum through a process called co-translational translocation .

  8. Pribnow box - Wikipedia

    en.wikipedia.org/wiki/Pribnow_box

    The Pribnow box has a function similar to the TATA box that occurs in promoters in eukaryotes and archaea: it is recognized and bound by a subunit of RNA polymerase during initiation of transcription. [3] This region of the DNA is also the first place where base pairs separate during prokaryotic transcription to allow access to the template strand.

  9. Transcription-translation coupling - Wikipedia

    en.wikipedia.org/wiki/Transcription-translation...

    While transcription-translation coupling is likely prevalent across prokaryotic organisms, not all species are dependent on it. Unlike Escherichia coli , in Bacillus subtilis transcription significantly outpaces translation, and coupling consequently does not occur.
