    Transcription is the process of copying a segment of DNA into RNA. ... for example, pathogenic bacteria ... allowing for detailed analyses of RNA in tissues, ...

  3. Primary transcript - Wikipedia

    en.wikipedia.org/wiki/Primary_transcript

    To initiate the transcription process in a cell's nucleus, DNA double helices are unwound and hydrogen bonds connecting compatible nucleic acids of DNA are broken to produce two unconnected single DNA strands. [1] One strand of the DNA template is used for transcription of the single-stranded primary transcript mRNA.

  4. Phonetic transcription - Wikipedia

    en.wikipedia.org/wiki/Phonetic_transcription

    A transcription which includes some allophonic detail but is still closely linked to the phonemic structure of an utterance is called an allophonic transcription. The advantage of narrower transcription is that it can help learners to produce exactly the right sound and allows linguists to make detailed analyses of language variation. [4]

  5. Eukaryotic transcription - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_transcription

    Eukaryotic Transcription. Eukaryotic transcription is the elaborate process that eukaryotic cells use to copy genetic information stored in DNA into units of transportable complementary RNA replica. [1] Gene transcription occurs in both eukaryotic and prokaryotic cells. Unlike prokaryotic RNA polymerase that initiates the transcription of all ...

  6. Bacterial transcription - Wikipedia

    en.wikipedia.org/wiki/Bacterial_transcription

    Bacterial transcription is the process in which a segment of bacterial DNA is copied into a newly synthesized strand of messenger RNA (mRNA) with use of the enzyme RNA polymerase. The process occurs in three main steps: initiation, elongation, and termination; and the result is a strand of mRNA that is complementary to a single strand of DNA.

  7. Transcriptional regulation - Wikipedia

    en.wikipedia.org/wiki/Transcriptional_regulation

    This process is called promoter escape, and is another step at which regulatory elements can act to accelerate or slow the transcription process. Similarly, protein and nucleic acid factors can associate with the elongation complex and modulate the rate at which the polymerase moves along the DNA template.

  8. Post-transcriptional modification - Wikipedia

    en.wikipedia.org/wiki/Post-transcriptional...

    One example is the conversion of precursor messenger RNA transcripts into mature messenger RNA that is subsequently capable of being translated into protein. This process includes three major steps that significantly modify the chemical structure of the RNA molecule: the addition of a 5' cap , the addition of a 3' polyadenylated tail, and RNA ...
