  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).

  3. Translation (biology) - Wikipedia

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

    First, convert each template DNA base to its RNA complement (note that the complement of A is now U), as shown below. Note that the template strand of the DNA is the one the RNA is polymerized against; the other DNA strand would be the same as the RNA, but with thymine instead of uracil. DNA -> RNA A -> U T -> A C -> G G -> C A=T-> A=U

  4. 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 ...

  5. Central dogma of molecular biology - Wikipedia

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

    Transcription is the process by which the information contained in a section of DNA is replicated in the form of a newly assembled piece of messenger RNA (mRNA). Enzymes facilitating the process include RNA polymerase and transcription factors. In eukaryotic cells the primary transcript is pre-mRNA. Pre-mRNA must be processed for translation to ...

  6. Gene expression - Wikipedia

    en.wikipedia.org/wiki/Gene_expression

    In general gene expression is regulated through changes [44] in the number and type of interactions between molecules [45] that collectively influence transcription of DNA [46] and translation of RNA. [47] Some simple examples of where gene expression is important are: Control of insulin expression so it gives a signal for blood glucose regulation.

  7. 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.

  8. Gene structure - Wikipedia

    en.wikipedia.org/wiki/Gene_structure

    Gene structure is the organisation of specialised sequence elements within a gene.Genes contain most of the information necessary for living cells to survive and reproduce. [1] [2] In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene.

  9. Protein biosynthesis - Wikipedia

    en.wikipedia.org/wiki/Protein_biosynthesis

    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). This conversion is carried out by enzymes, known as RNA polymerases, in the nucleus of the cell. [2]
