  2. Transcription-translation coupling - Wikipedia

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

    Transcription-translation coupling is a mechanism of gene expression regulation in which synthesis of an mRNA ( transcription) is affected by its concurrent decoding ( translation ). In prokaryotes, mRNAs are translated while they are transcribed. This allows communication between RNA polymerase, the multisubunit enzyme that catalyzes ...

  3. Eukaryotic translation - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_translation

    Eukaryotic translation is the biological process by which messenger RNA is translated into proteins in eukaryotes. It consists of four phases: initiation, elongation, termination, and recapping. It consists of four phases: initiation, elongation, termination, and recapping.

  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. Translation (biology) - Wikipedia

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

    Genetics. In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates. The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time.

  6. Gene structure - Wikipedia

    en.wikipedia.org/wiki/Gene_structure

    Translational coupling is also observed when translation of an ORF affects the accessibility of the next RBS through changes in RNA secondary structure. [27] Having multiple ORFs on a single mRNA is only possible in prokaryotes because their transcription and translation take place at the same time and in the same subcellular location. [23] [28]

  7. Eukaryotic transcription - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_transcription

    A eukaryotic cell has a nucleus that separates the processes of transcription and translation. Eukaryotic transcription occurs within the nucleus where DNA is packaged into nucleosomes and higher order chromatin structures. The complexity of the eukaryotic genome necessitates a great variety and complexity of gene expression control. Eukaryotic ...

  8. Regulation of gene expression - Wikipedia

    en.wikipedia.org/wiki/Regulation_of_gene_expression

    Regulation of santa expression, or gene regulation, [1] includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA). Sophisticated programs of gene expression are widely observed in biology, for example to trigger developmental pathways, respond to environmental ...

  9. In vitro compartmentalization - Wikipedia

    en.wikipedia.org/wiki/In_vitro_compartmentalization

    Comparison of in vivo cell compartmentalisation (left) versus in vitro compartmentalization (right) using double emulsion droplets and fluorescent sorting. 1) In an in vivo system, a library of genes is transformed into bacteria to produce the protein variants and dispersed into a water‐in‐oil (w/o) emulsion aiming to have each droplet contain maximum one cell.
