The distribution of DNA CsCl band asymmetries for all fish species investigated are presented in the histogram of Fig. 4.2B. The majority of fishes showed asymmetry values around 0.5 mg/cm (A = 0.65 mg/cm a = 0.54 mg/cm in the case of Actinopterygii).

In addition to Giardia, it is likely that mitosomes are present in other related diplomonads, such as the fish parasite Spironucleus. A recent genomic survey of this organism indicated the presence of IscS in this parasite, which might be localized in putative mitosomes (Andersson et al. 2007). However,... 

A second Drosophila transposon called mariner630 typifies the mariner / Tel transposon superfamily, which also contains members from nematodes,631 other invertebrates, fishes,632 amphibia,633 and possibly human beings.634 These transposons encode a transposase containing a D, D, D or D, D, E motif630 but no other proteins. They contain short 30-bp terminal inverted repeats and become inserted into host TA sequences.631 Movement of some repetitive sequences of the LINE635 and SINE636 families within the human genome may be assisted by mariner transposons.637...
