  2. Messenger RNA - Wikipedia

    en.wikipedia.org/wiki/Messenger_RNA

    Translation of mRNA to protein. Because prokaryotic mRNA does not need to be processed or transported, translation by the ribosome can begin immediately after the end of transcription. Therefore, it can be said that prokaryotic translation is coupled to transcription and occurs co-transcriptionally. [23]

  3. Translation regulation by 5′ transcript leader cis-elements

    en.wikipedia.org/wiki/Translation_regulation_by_5...

    Alterations in translation of mRNA into proteins rapidly modulates the proteome without changing upstream steps such as transcription, pre-mRNA splicing, and nuclear export. [1] The strict regulation of translation in both space and time is in part governed by cis-regulatory elements located in 5′ mRNA transcript leaders (TLs) and 3 ...

  4. Translation (biology) - Wikipedia

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

    termination of translation, degradation of mRNA molecules, degradation of proteins. The process of amino acid building to create protein in translation is a subject of various physic models for a long time starting from the first detailed kinetic models such as [26] or others taking into account stochastic aspects of translation and using ...

  5. Central dogma of molecular biology - Wikipedia

    en.wikipedia.org/wiki/Central_dogma_of_molecular...

    Pre-mRNA must be processed for translation to proceed. Processing includes the addition of a 5' cap and a poly-A tail to the pre-mRNA chain, followed by splicing. Alternative splicing occurs when appropriate, increasing the diversity of the proteins that any single mRNA can produce. The product of the entire transcription process (that began ...

  6. Protein biosynthesis - Wikipedia

    en.wikipedia.org/wiki/Protein_biosynthesis

    Protein synthesis is a very similar process for both prokaryotes and eukaryotes but there are some distinct differences. [1] Protein synthesis can be divided broadly into two phases: transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a molecule called messenger RNA (mRNA).

  7. Eukaryotic translation - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_translation

    Unlike bacteria, in which translation initiation occurs as soon as the 5' end of an mRNA is synthesized, in eukaryotes, such tight coupling between transcription and translation is not possible because transcription and translation are carried out in separate compartments of the cell (the nucleus and cytoplasm).

  8. Protein metabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_metabolism

    The steps of protein synthesis include transcription, translation, and post translational modifications. During transcription, RNA polymerase transcribes a coding region of the DNA in a cell producing a sequence of RNA, specifically messenger RNA (mRNA). This mRNA sequence contains codons: 3 nucleotide long segments that code for a specific ...

  9. 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).
