  2. Retroposon - Wikipedia

    en.wikipedia.org/wiki/Retroposon

    Non-long terminal repeat (LTR) retrotransposons such as the human LINE1 elements are sometimes falsely referred to as retroposons. However, this depends on the author. For example, Howard Temin published the following definition: Retroposons encode RT but are devoid of long terminal repeats (LTRs), for example long interspersed elements (LINEs).

  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...

    Remnants of L2 and L3 elements are found in the human genome. [23] It is estimated that L2 and L3 elements were active ~200-300 million years ago. Due to the age of L2 elements found within therian genomes, they lack flanking target site duplications. [24]

  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. 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 ...

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  9. Alu element - Wikipedia

    en.wikipedia.org/wiki/Alu_element

    An Alu element is a short stretch of DNA originally characterized by the action of the Arthrobacter luteus (Alu) restriction endonuclease. [1] Alu elements are the most abundant transposable elements in the human genome, present in excess of one million copies. [2]
