  2. Transcription (biology) - Wikipedia

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

    Transcription is the process of copying a segment of DNA into RNA for the purpose of gene expression. Some segments of DNA are transcribed into RNA molecules that can encode proteins, called messenger RNA (mRNA). Other segments of DNA are transcribed into RNA molecules called non-coding RNAs (ncRNAs).

  3. Transcriptome - Wikipedia

    en.wikipedia.org/wiki/Transcriptome

    The word transcriptome is a portmanteau of the words transcript and genome.It appeared along with other neologisms formed using the suffixes -ome and -omics to denote all studies conducted on a genome-wide scale in the fields of life sciences and technology.

  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. Transcriptomics technologies - Wikipedia

    en.wikipedia.org/wiki/Transcriptomics_technologies

    Transcriptomics technologies are the techniques used to study an organism's transcriptome, the sum of all of its RNA transcripts.The information content of an organism is recorded in the DNA of its genome and expressed through transcription.

  6. Transcriptional regulation - Wikipedia

    en.wikipedia.org/wiki/Transcriptional_regulation

    The power of transcription factors resides in their ability to activate and/or repress wide repertoires of downstream target genes. The fact that these transcription factors work in a combinatorial fashion means that only a small subset of an organism's genome encodes transcription factors.

  7. Transcription - Wikipedia

    en.wikipedia.org/wiki/Transcription

    Transcription (linguistics), the representations of speech or signing in written form Orthographic transcription, a transcription method that employs the standard spelling system of each target language; Phonetic transcription, the representation of specific speech sounds or sign components; service and software

  8. Primary transcript - Wikipedia

    en.wikipedia.org/wiki/Primary_transcript

    All these steps involve a series of interactions to initiate and complete the transcription of DNA in the nucleus of eukaryotes. Certain factors play key roles in the activation and inhibition of transcription, where they regulate primary transcript production. Transcription produces primary transcripts that are further modified by several ...

  9. 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 ...
