|description=''Boudicca'' is a ''CsRN1''-like LTR retrotransposon described in the genome of the trematode ''Schistosoma mansoni'' ([[Literature:14757|Copeland ''et al''. 2003]]; [[Literature:14756| 2004]]). More than 1000 copies of ''Boudicca'' are present in the genome of this organism, although many of them may be degenerate and inactive ([[Literature:14757|Copeland ''et al''. 2003]]; [[Literature:14756| 2004]]). Boudicca is also present in S. haematobium and it is possible that ''Boudicca-''like retrotransposons would be represented in the genome of ''Betaeus truncatus'', the snail host of ''S. haematobium'' ([[Literature:14754|Copeland ''et al''. 2006]]).

The genome structure of ''Boudicca'' is 5.8 Kb in size, including LTRs of 327-301 nt long. The internal region of ''Boudicca'' displays a Primer Binding Site, four Open Reading Frames (ORFs), as well as a Polypurine Tract (PPT) adjacent to the 3’ LTR. ORF1 and ORF 2 encode for the Gag and pol polyproteins typical of LTR retrotransposons. ORF3 is the GPYF module of INT separated by a stop codon and ORF codes for a putative small peptide of unknown function (for more details, see [[Literature:14757|Copeland ''et al''. 2003]]; [[Literature:14756| 2004]]).
