  2. Prokaryotic translation - Wikipedia

    en.wikipedia.org/wiki/Prokaryotic_translation

    Prokaryotic translation may refer to: Bacterial translation, the process by which messenger RNA is translated into proteins in bacteria; Archaeal translation, the ...

  3. Translation (biology) - Wikipedia

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

    For example, research utilizing this method has revealed that genetic differences and their subsequent expression as mRNAs can also impact translation rate in an RNA-specific manner. [ 21 ] Expanding on this concept, a more recent development is single-cell ribosome profiling, a technique that allows us to study the translation process at the ...

  4. 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 ...

  5. Internal ribosome entry site - Wikipedia

    en.wikipedia.org/wiki/Internal_ribosome_entry_site

    An internal ribosome entry site, abbreviated IRES, is an RNA element that allows for translation initiation in a cap-independent manner, as part of the greater process of protein synthesis.

  6. 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 ...

  7. Translational regulation - Wikipedia

    en.wikipedia.org/wiki/Translational_regulation

    Due to the fact that translation elongation is an irreversible process, there are few known mechanisms of its regulation. However, it has been shown that translational efficiency is reduced via diminished tRNA pools, which are required for the elongation of polypeptides.

  8. Transcription-translation coupling - Wikipedia

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

    Translation promotes transcription elongation and regulates transcription termination. Functional coupling between transcription and translation is caused by direct physical interactions between the ribosome and RNA polymerase ("expressome complex"), ribosome-dependent changes to nascent mRNA secondary structure which affect RNA polymerase activity (e.g. "attenuation"), and ribosome-dependent ...

  9. Primary transcript - Wikipedia

    en.wikipedia.org/wiki/Primary_transcript

    The primary transcripts designated to be mRNAs are modified in preparation for translation. For example, a precursor mRNA (pre-mRNA) is a type of primary transcript that becomes a messenger RNA (mRNA) after processing. Pre-mRNA is synthesized from a DNA template in the cell nucleus by transcription. Pre-mRNA comprises the bulk of heterogeneous ...
