  2. Reading frame - Wikipedia

    en.wikipedia.org/wiki/Reading_frame

    An open reading frame (ORF) is a reading frame that has the potential to be transcribed into RNA and translated into protein. It requires a continuous sequence of DNA which may include a start codon, through a subsequent region which has a length that is a multiple of 3 nucleotides, to a stop codon in the same reading frame.

  3. Open reading frame - Wikipedia

    en.wikipedia.org/wiki/Open_reading_frame

    Since DNA is interpreted in groups of three nucleotides (codons), a DNA strand has three distinct reading frames. [15] The double helix of a DNA molecule has two anti-parallel strands; with the two strands having three reading frames each, there are six possible frame translations. [15] Example of a six-frame translation.

  4. DNA annotation - Wikipedia

    en.wikipedia.org/wiki/DNA_annotation

    Whereas prokaryotic CDS predictors mostly deal with open reading frames (ORFs), which are segments of DNA between the start and stop codons, eukaryotic CDS predictors are faced with a more difficult problem because of the complex organization of eukaryotic genes. [3] CDS prediction methods can be classified into three broad categories: [2] [31]

  5. Upstream open reading frame - Wikipedia

    en.wikipedia.org/wiki/Upstream_open_reading_frame

    An upstream open reading frame (uORF) is an open reading frame (ORF) within the 5' untranslated region (5'UTR) of an mRNA. uORFs can regulate eukaryotic gene expression. [1] [2] Translation of the uORF typically inhibits downstream expression of the primary ORF. However, in some genes such as yeast GCN4, translation of specific uORFs may ...

  6. Overlapping gene - Wikipedia

    en.wikipedia.org/wiki/Overlapping_gene

    Out-of-phase overlaps occurs when the shared sequences use different reading frames. This can occur in "phase 1" or "phase 2", depending on whether the reading frames are offset by 1 or 2 nucleotides. Because a codon is three nucleotides long, an offset of three nucleotides is an in-phase, phase 0 frame.

  8. Five prime untranslated region - Wikipedia

    en.wikipedia.org/wiki/Five_prime_untranslated_region

    Another form of translational regulation in eukaryotes comes from unique elements on the 5′ UTR called upstream open reading frames (uORF). These elements are fairly common, occurring in 35–49% of all human genes. [18] A uORF is a coding sequence located in the 5′ UTR located upstream of the coding sequences initiation site.

  9. Regulatory sequence - Wikipedia

    en.wikipedia.org/wiki/Regulatory_sequence

    An active enhancer regulatory sequence of DNA is enabled to interact with the promoter DNA regulatory sequence of its target gene by formation of a chromosome loop. This can initiate messenger RNA (mRNA) synthesis by RNA polymerase II (RNAP II) bound to the promoter at the transcription start site of the gene. The loop is stabilized by one ...
