homologous segment

Sequences flanking tn5 in nm21 was cloned by anchored pcr . a 3073bp fragment which contains three putative open reading frames ( orf ) and shows strong homology with the magnetospirillum magnetotacticum ms - 1 was obtained , the tn5 inserted in the orf1
用锚定pcr法从nm21中克隆出tn5侧翼序列，得到一个大小为3073bp的dna片段，此片段由3个orf组成，与m . magnetotacticumms - 1的对应片段具有89的同源性。
