simple sequence dna
解釋
單一順序dna-
The random amplified polymorphic dna ( rapd ) and inter - simple sequence repeat ( issr ) analysis were used to estimate population genetics of fenneropenaeus chinensis. we analyzed the genetic diversity and genetic structure of the populations, and also studied the genetic divergency among populations and geographic populations. the main results shown as follows : 1
本文以中國對蝦（ fenneropenaeuschinensis ）野生群體為研究對象，採用rapd和issr分子標記技術，進行了群體遺傳學的研究，對中國對蝦野生群體的遺傳多樣性及群體遺傳結構進行了分析，研究了中國對蝦各野生群體之間的遺傳分化情況。 -
Objective : as one of the widest length polymorphic genetic markers, short tandem repeat ( str ), also named microsatellite dna or simple sequence repeats ( ssrs ), are currently used in forensic hematogenetics. the short tandem repeat loci are widely dispersed in the human genome and have high sensitivity and discrimination power
目的:短串聯重復序列（ shorttandemrepeats ， str ） ，又稱微衛星dna或簡單重復序列（ simplesequencerepeats ， ssrs ） ，是目前在法醫物證學中應用最廣泛的片段長度多態性遺傳標記。 -
90 individuals of 6 populations, including possible wild populations and cultivated populations, with some individuals from inside and outside of china were analyzed by inter - simple sequence repeats ( issr ) and random amplified polymorphic dna ( rapd ) markers to determine the genetic diversity and genetic variations of among and within the populations. in addition, the status of ginkgo resource in china has been investigated in this study. 1
本研究對中國的銀杏資源狀況進行了調查，並採用issr和rapd兩種分子標記技術，選取中國的6個銀杏群體（包括可能的野生群體和栽培群體）以及國內外一些零星分佈的銀杏個體，從保護生物學角度對其遺傳多樣性水平和群體遺傳結構進行了研究，獲得以下結果。 -
It is true in difficult cases, such as degraded dna or samples containing minimal amounts of genomic dna. to investigate the sequence diversity of mtdna in taiyuan han population, mtdna nt16081 - 16546 sequences were determined in 58 unrelated han chinese from taiyuan. sscp method was developed as one of screening measures which were used to examine polymorphism of mtdna, so as to supply a rapid and simple method for forensic casework
方法隨機抽取58名太原地區漢族群體無血緣關系個體的靜脈血， edta抗凝，改良的tkm法提取mtdna ， pcr擴增、純化后，應用377序列分析儀進行直接測序分析；對毛發、指甲、骨骼等微量或嚴重降解檢材進行mtdna序列分析；採集同一屍體血液、肌肉、肝、腎、心肌、不同部位的毛乾等組織進行同一性檢測；對20個兩代家系進行突變觀察。
