  2. Retroposon - Wikipedia

    en.wikipedia.org/wiki/Retroposon

    A classical event is the retroposition of a spliced pre-mRNA molecule of the c-Src gene into the proviral ancestor of the Rous sarcoma virus (RSV). The retroposed c-src pre-mRNA still contained a single intron and within RSV is now referred to as v-Src gene.

  3. Retrotransposon - Wikipedia

    en.wikipedia.org/wiki/Retrotransposon

    An endogenous retrovirus is a retrovirus without virus pathogenic effects that has been integrated into the host genome by inserting their inheritable genetic information into cells that can be passed onto the next generation like a retrotransposon. [8]

  4. LTR retrotransposon - Wikipedia

    en.wikipedia.org/wiki/LTR_retrotransposon

    LTR retrotransposons have direct long terminal repeats that range from ~100 bp to over 5 kb in size. LTR retrotransposons are further sub-classified into the Ty1-copia-like (Pseudoviridae), Ty3-like (Metaviridae, formally referred to as Gypsy-like, a name that is being considered for retirement [4]), and BEL-Pao-like (Belpaoviridae) groups based on both their degree of sequence similarity and ...

  5. Long interspersed nuclear element - Wikipedia

    en.wikipedia.org/wiki/Long_interspersed_nuclear...

    Of these, L1, L2 and L3 elements made up 516,000, 315,000 and 37,000 copies, respectively. The non-autonomous SINE elements which depend on L1 elements for their proliferation make up 13% of the human genome and have a copy number of around 1.5 million. [ 23 ]

  6. Transposable element - Wikipedia

    en.wikipedia.org/wiki/Transposable_element

    A bacterial DNA transposon. A transposable element (TE), also transposon, or jumping gene, is a type of mobile genetic element, a nucleic acid sequence in DNA that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size.

  7. LINE1 - Wikipedia

    en.wikipedia.org/wiki/LINE1

    A typical L1 element is approximately 6,000 base pairs (bp) long and consists of two non-overlapping open reading frames (ORFs) which are flanked by untranslated regions (UTRs) and target site duplications.

  8. PiggyBac transposon system - Wikipedia

    en.wikipedia.org/wiki/PiggyBac_Transposon_System

    The PiggyBac (PB) transposon system employs a genetically engineered transposase enzyme to insert a gene into a cell's genome. It is built upon the natural PiggyBac (PB) transposable element (transposon), enabling the back and forth movement of genes between chromosomes and genetic vectors such as plasmids through a "cut and paste" mechanism.

  9. Retrotransposon marker - Wikipedia

    en.wikipedia.org/wiki/Retrotransposon_marker

    Retrotransposon markers are components of DNA which are used as cladistic markers. They assist in determining the common ancestry, or not, of related taxa.The "presence" of a given retrotransposon in related taxa suggests their orthologous integration, a derived condition acquired via a common ancestry, while the "absence" of particular elements indicates the plesiomorphic condition prior to ...
