  2. Termination signal - Wikipedia

    en.wikipedia.org/wiki/Termination_signal

    Termination signals bring a stop to transcription, ensuring that only gene-encoding parts of the chromosome are transcribed. [1] Transcription begins at the promoter when RNA polymerase , an enzyme that facilitates transcription of DNA into mRNA, binds to a promoter , unwinds the helical structure of the DNA, and uses the single-stranded DNA as ...

  3. Open reading frame - Wikipedia

    en.wikipedia.org/wiki/Open_reading_frame

    That start codon (not necessarily the first) indicates where translation may start. The transcription termination site is located after the ORF, beyond the translation stop codon. If transcription were to cease before the stop codon, an incomplete protein would be made during translation. [3]

  4. Start codon - Wikipedia

    en.wikipedia.org/wiki/Start_codon

    The start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome. The start codon always codes for methionine in eukaryotes and archaea and a N-formylmethionine (fMet) in bacteria, mitochondria and plastids .

  5. Stop codon - Wikipedia

    en.wikipedia.org/wiki/Stop_codon

    Stop codon (red dot) of the human mitochondrial DNA MT-ATP8 gene, and start codon (blue circle) of the MT-ATP6 gene. For each nucleotide triplet (square brackets), the corresponding amino acid is given (one-letter code), either in the +1 reading frame for MT-ATP8 (in red) or in the +3 frame for MT-ATP6 (in blue).

  6. Terminator (genetics) - Wikipedia

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

    In genetics, a transcription terminator is a section of nucleic acid sequence that marks the end of a gene or operon in genomic DNA during transcription.This sequence mediates transcriptional termination by providing signals in the newly synthesized transcript RNA that trigger processes which release the transcript RNA from the transcriptional complex.

  7. Eukaryotic translation - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_translation

    Translation initiation is the process by which the ribosome and its associated factors bind to an mRNA and are assembled at the start codon. This process is defined as either cap-dependent, in which the ribosome binds initially at the 5' cap and then travels to the stop codon, or as cap-independent, where the ribosome does not initially bind ...

  8. Bacterial transcription - Wikipedia

    en.wikipedia.org/wiki/Bacterial_transcription

    In order for proper gene expression to occur, transcription must stop at specific sites. Two termination mechanisms are well known: Intrinsic termination (also called Rho-independent termination): Specific DNA nucleotide sequences signal the RNA polymerase to stop.

  9. Antitermination - Wikipedia

    en.wikipedia.org/wiki/Antitermination

    The role of NusG in the N antitermination reaction is not clear. NusG binds to termination factor Rho and to RNAP. It stimulates the rate of transcription elongation and is required for the activity of certain Rho-dependent terminators. NusG is a component of the complete antitermination complex and enhances N antitermination in vitro.
