Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A sequence of DNA in a chromosome that arose by the copying of an RNA virus into DNA by reverse transcriptase and integration of the DNA copy into the chromosome.
- ‘Seitz et al. observed that, in mice, certain microRNAs were transcribed only in the maternal genome while a homologous retroelement was transcribed only in the paternal genome.’
- ‘Recent genome sequence analyses have shown the quantitative importance of retroelements.’
- ‘The molecular organization of both tandem repeats and retroelements into specific chromosomal regions, as revealed by sequencing and FISH analysis, allows cursory insight into the organization of the soybean genome.’
- ‘As the analysis of retroelements continues, not only their abundance in genomes, but also the great plasticity apparent in their structure is becoming clearer.’
- ‘In tomato and other plant species, greatly reduced rates of recombination are observed near and on centromeric regions and in retroelements, transposons, and other highly repetitive regions.’
