1. Lesões típicas da Doença de Chagas em aves com genoma alterado por integração de seqüências de minicírculos de kDNA de Trypanosoma cruzi
Acredita-se que a origem e evolução dos seres vivos foram antecedidas por uma complexa rede de interações entre moléculas, microrganismos e células em metazoários. Nesse processo, inúmeros eventos de rearranjo e transferência gênica teriam concorrido para o aumento da complexidade do genoma dos seres hoje existentes. O acúmulo de moléculas de DNA

2. Chicken repeat 1 elements contain a pol-like open reading frame and belong to the non-long terminal repeat class of retrotransposons.
Chicken genomes contain approximately 30,000 chicken repeat 1 (CR1) elements scattered among single-copy sequences, but no information has yet been presented to account for how these elements could have dispersed. The fact that CR1 elements have common (although atypical) 3' ends and variable 5' truncations suggested to us that they might belong to the class

3. The 3' ends of tRNA-derived short interspersed repetitive elements are derived from the 3' ends of long interspersed repetitive elements.
Short interspersed repetitive elements (SINEs) are a type of retroposon, being members of a class of informational molecules that are amplified via cDNA intermediates and flow back into the host genome. In contrast to retroviruses and retrotransposons, SINEs do not encode the enzymes required for their amplification, such as reverse transcriptases, so they a
