  2. Transcription (biology) - Wikipedia

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

    During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript. In virology, the term transcription is used when referring to mRNA synthesis from a viral RNA molecule.

  3. 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.

  4. Eukaryotic transcription - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_transcription

    t. e. 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 ...

  5. Introduction to genetics - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_genetics

    A section of DNA; the sequence of the plate-like units (nucleotides) in the center carries information. Genes are pieces of DNA that contain information for the synthesis of ribonucleic acids (RNAs) or polypeptides. Genes are inherited as units, with two parents dividing out copies of their genes to their offspring.

  6. Transcription factor - Wikipedia

    en.wikipedia.org/wiki/Transcription_factor

    transcription – the process of making messenger RNA (mRNA) from a DNA template by RNA polymerase. transcription factor – a protein that binds to DNA and regulates gene expression by promoting or suppressing transcription. transcriptional regulation – controlling the rate of gene transcription for example by helping or hindering RNA ...

  7. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    For example, in transcription, when a cell uses the information in a gene, the DNA sequence is copied into a complementary RNA sequence through the attraction between the DNA and the correct RNA nucleotides.

  8. 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. The process occurs in three main steps: initiation, elongation, and termination; and the end ...

  9. General transcription factor - Wikipedia

    en.wikipedia.org/wiki/General_transcription_factor

    A transcription factor is a protein that binds to specific DNA sequences (enhancer or promoter), either alone or with other proteins in a complex, to control the rate of transcription of genetic information from DNA to messenger RNA by promoting (serving as an activator) or blocking (serving as a repressor) the recruitment of RNA polymerase. [3 ...
