  2. Transcription (biology) - Wikipedia

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

    The process of transcription is a major source of DNA damage, due to the formation of single-strand DNA intermediates that are vulnerable to damage. [53] The regulation of transcription by processes using base excision repair and/or topoisomerases to cut and remodel the genome also increases the vulnerability of DNA to damage. [53]

  3. 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 ...

  4. General transcription factor - Wikipedia

    en.wikipedia.org/wiki/General_transcription_factor

    The transcription preinitiation complex is a large complex of proteins that is necessary for the transcription of protein-coding genes in eukaryotes and archaea. It attaches to the promoter of the DNA (e.i., TATA box) and helps position the RNA polymerase II to the gene transcription start sites, denatures the DNA, and then starts transcription.

  5. Gene expression - Wikipedia

    en.wikipedia.org/wiki/Gene_expression

    Several cell function-specific transcription factors (among the about 1,600 transcription factors in a human cell) [68] generally bind to specific motifs on an enhancer. [69] A small combination of these enhancer-bound transcription factors, when brought close to a promoter by a DNA loop, govern transcription level of the target gene.

  6. Transcription factor - Wikipedia

    en.wikipedia.org/wiki/Transcription_factor

    Other transcription factors differentially regulate the expression of various genes by binding to enhancer regions of DNA adjacent to regulated genes. These transcription factors are critical to making sure that genes are expressed in the right cell at the right time and in the right amount, depending on the changing requirements of the organism.

  7. Transcriptional regulation - Wikipedia

    en.wikipedia.org/wiki/Transcriptional_regulation

    In molecular biology and genetics, transcriptional regulation is the means by which a cell regulates the conversion of DNA to RNA (transcription), thereby orchestrating gene activity.

  8. Transcriptome - Wikipedia

    en.wikipedia.org/wiki/Transcriptome

    Transcription can also be studied at the level of individual cells by single-cell transcriptomics. Single-cell RNA sequencing (scRNA-seq) is a recently developed technique that allows the analysis of the transcriptome of single cells, including bacteria . [ 25 ]

  9. Bacterial transcription - Wikipedia

    en.wikipedia.org/wiki/Bacterial_transcription

    Transcription is the process of copying DNA into RNA, usually mRNA.. 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.
