  2. Terminator (genetics) - Wikipedia

    en.wikipedia.org/wiki/Terminator_(genetics)

    In genetics, a transcription terminator is a section of nucleic acid sequence that marks the end of a gene or operon in genomic DNA during transcription.This sequence mediates transcriptional termination by providing signals in the newly synthesized transcript RNA that trigger processes which release the transcript RNA from the transcriptional complex.

  3. Termination signal - Wikipedia

    en.wikipedia.org/wiki/Termination_signal

    Once RNA polymerase reaches the termination signal, transcription is terminated. [1] In bacteria, there are two main types of termination signals: intrinsic and factor-dependent terminators. [1] In the context of translation, a termination signal is the stop codon on the mRNA that elicits the release of the growing peptide from the ribosome. [2]

  4. 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.

  5. Gene gun - Wikipedia

    en.wikipedia.org/wiki/Gene_gun

    Terminator Terminator sequences are required for proper gene expression and are placed after the coding region of the gene of interest within the DNA construct. A common terminator for biolistic transformation is the NOS terminator derived from Agrobacterium tumefaciens. Due to the high frequency of use of this terminator in genetically ...

  6. DNA and RNA codon tables - Wikipedia

    en.wikipedia.org/wiki/DNA_and_RNA_codon_tables

    [2] [3] The mRNA sequence is determined by the sequence of genomic DNA. [4] In this context, the standard genetic code is referred to as translation table 1. [3] It can also be represented in a DNA codon table. The DNA codons in such tables occur on the sense DNA strand and are arranged in a 5 ′-to-3 ′ direction.

  7. Ter site - Wikipedia

    en.wikipedia.org/wiki/Ter_site

    They are required for the termination of DNA replication and function by binding to DNA replication terminator sequences, thus preventing the passage of replication forks. [1] The termination efficiency is affected by the affinity of a particular protein for the terminator sequence .

  8. Genetic code - Wikipedia

    en.wikipedia.org/wiki/Genetic_code

    Reading frames in the DNA sequence of a region of the human mitochondrial genome coding for the genes MT-ATP8 and MT-ATP6 (in black: positions 8,525 to 8,580 in the sequence accession NC_012920 [31]). There are three possible reading frames in the 5' → 3' forward direction, starting on the first (+1), second (+2) and third position (+3).

  9. Antitermination - Wikipedia

    en.wikipedia.org/wiki/Antitermination

    Termination can be controlled with the same sort of precision as initiation. The antitermination activity of pN is highly specific, but the antitermination event is not determined by the terminators t L1 and t R1 ; the recognition site needed for antitermination lies upstream in the transcription unit, that is, at a different place from the ...
