摘要: It is believed that short interspersed elements (SINEs) are irreversibly inserted into genomes. We use this concept to try deduce the evolution of whales using sequence and hybridization studies. The observation microsatellites associated with SINEs lead us screen sequences surrounding cetacean for artiodactyl-derived SINEs. Two were thought be bovine SINE aligned comparison flanking from ungulates. was observed only in ruminants while CetSINE1 2 found mammals. Hybridization studies these three revealed all ungulates cetaceans strongest signal hippopotamus beluga; CetSINE2 hybridized ungulate suborders, Ruminantia. proposed putative not 'generic' but mammalian-wide repeats (MIRs). Caution urged: what initially appears a may instead MIR have reduced evolutionary resolving power.
