There are 4 types in these sequences : DNA transposons , LTR retrotransposons , LINE retrotransposons and rolling circles .

当一个基因遭破坏后被发现，这时可以通过搜索转座子DNA以及鉴定转座子DNA周围的区域对遭受破坏的基因进行识别和鉴定。

When a gene disruption is found , it can be identified and characterized by looking for the transposon DNA and then characterizing the surrounding region .
