▁are ▁ 3 3 ▁par alog ous ▁sequences ▁with ▁over ▁ 8 0 % ▁sequence ▁similarity ▁and ▁of ▁a ▁greater ▁length ▁than ▁ 5 0 0 ▁b p . ▁Moreover , ▁not ▁all ▁the ▁NUM T ▁fragments ▁in ▁the ▁gen ome ▁are ▁the ▁result ▁of ▁m t D NA ▁migration ; ▁some ▁are ▁the ▁outcome ▁of ▁ampl ification ▁after ▁insert ion . ▁Old ▁NUM T s ▁are ▁found ▁to ▁be ▁more ▁abund ant ▁in ▁the ▁human ▁gen ome ▁than ▁the ▁recent ▁integr ants , ▁indicating ▁that ▁m t D NA ▁can ▁be ▁ampl ified ▁once ▁inserted . ▁Day ama ▁et ▁al . ▁developed ▁a ▁high ▁yield ▁new ▁technique ▁for ▁the ▁exact ▁detection ▁of ▁the ▁number ▁of ▁NUM T ▁in ▁the ▁human ▁gen ome ▁called ▁din um t . ▁This ▁method ▁enables ▁her ▁and ▁her ▁team ▁members ▁to ▁identify ▁NUM T ▁insert ions , ▁of ▁all ▁sizes , ▁in ▁the ▁whole ▁genom es ▁sequ enced ▁using ▁pa ired - end ▁sequ encing ▁technology ▁with ▁a ▁greater ▁sens itivity . ▁They ▁applied ▁din um t ▁to ▁ 9 9 9 ▁individuals ▁from ▁the ▁ 1 0 0 0 ▁Gen om es ▁Project ▁and ▁Human ▁Gen ome ▁D iversity ▁Project ▁( H G DP ) ▁and ▁conducted ▁an ▁updated ▁en rich ment ▁analysis ▁in ▁humans ▁using ▁these ▁polym orph ic ▁insert ions . ▁Further ▁investigation ▁and ▁gen ot yp ing ▁of ▁the ▁discovered ▁NUM T ▁also ▁anal ys es ▁age ▁of ▁insert ion , ▁origin , ▁and ▁sequence ▁characteristics . ▁Finally ▁they ▁ass essed ▁their ▁potential
