  2. Long terminal repeat - Wikipedia

    en.wikipedia.org/wiki/Long_terminal_repeat

    A long terminal repeat (LTR) is a pair of identical sequences of DNA, several hundred base pairs long, which occur in eukaryotic genomes on either end of a series of genes or pseudogenes that form a retrotransposon or an endogenous retrovirus or a retroviral provirus. All retroviral genomes are flanked by LTRs, while there are some ...

  4. Trans-activation response element - Wikipedia

    en.wikipedia.org/wiki/Trans-activation_response...

    The HIV trans-activation response (TAR) element is an RNA element which is known to be required for the trans-activation of the viral promoter and for virus replication. The TAR hairpin is a dynamic structure [1] that acts as a binding site for the Tat protein, and this interaction stimulates the activity of the long terminal repeat promoter.

  5. Retrotransposon - Wikipedia

    en.wikipedia.org/wiki/Retrotransposon

    They are only present in eukaryotes but share features with retroviruses such as HIV, for example, discontinuous reverse transcriptase-mediated extrachromosomal recombination. [5] [6] There are two main types of retrotransposons, long terminal repeats (LTRs) and non-long terminal repeats (non-LTRs).

  6. Lentivirus - Wikipedia

    en.wikipedia.org/wiki/Lentivirus

    Genome sequence has terminal repeated sequences; long terminal repeats (LTR) (of about 600 nt) The 5' end of the genome has a cap; Cap sequence of type 1 m7G5ppp5'GmpNp; 3' end of each monomer has a poly (A) tract. 2 copies packed per particle (held together by Watson-Crick baseparing to form a dimer). There are 11 proteins Virions contain 60% ...

  7. 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 ...
