  2. Sigma factor - Wikipedia

    en.wikipedia.org/wiki/Sigma_factor

    The model consists of a two-step process of gene expression (transcription followed by translation). The rate constant from transcription (k t) accounts for the possibility of binding by either RNAP (those carrying sigma 70, and those carrying sigma 38). The model also includes translation (rate constant kt), and RNA and protein degradation to ...

  3. Transformation efficiency - Wikipedia

    en.wikipedia.org/wiki/Transformation_efficiency

    In molecular biology, transformation efficiency is a crucial parameter, it is used to evaluate the ability of different methods to introduce plasmid DNA into cells and to compare the efficiency of different plasmid, vectors and host cells. This efficiency can be affected by a number of factors, including the method used for introducing the DNA ...

  4. Guanosine triphosphate - Wikipedia

    en.wikipedia.org/wiki/Guanosine_triphosphate

    Guanosine-5'-triphosphate (GTP) is a purine nucleoside triphosphate. It is one of the building blocks needed for the synthesis of RNA during the transcription process. Its structure is similar to that of the guanosine nucleoside, the only difference being that nucleotides like GTP have phosphates on their ribose sugar.

  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. Hill equation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Hill_equation_(biochemistry)

    In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration. A ligand is "a substance that forms a complex with a biomolecule to serve a biological purpose" (ligand definition), and a macromolecule is a very large ...

  7. 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 ...

  8. Transcriptional regulation - Wikipedia

    en.wikipedia.org/wiki/Transcriptional_regulation

    transcriptional regulation – controlling the rate of gene transcription for example by helping or hindering RNA polymerase binding to DNA. transcription – the process of making RNA from a DNA template by RNA polymerase. transcription factor – a substance, such as a protein, that contributes to the cause of a specific biochemical reaction ...

  9. Bacterial transcription - Wikipedia

    en.wikipedia.org/wiki/Bacterial_transcription

    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 result is a strand of mRNA that is complementary to a single strand of DNA.
