we found a multi-copy repeat sequence in zebrafish genome (all chromosomes), by our new method DHPC. We suspected that they are a new transposon, this idea is vertifiedby EST blast. but we are not biologists, we hope to cooperate with biologists in this work. who is interested in this work can cantact us by email dengxuegong@tom.com any one who isfamiliar with this problem can give me some suggestions? the repeat sequence (2kb) has about 1000 copies. not found any copy in other fish or animal, even though low similar level. if one know who is the expert in this problem tell me please. thanks !
