nucleotide transversion 中文意思是什麼
-
( 3 ) the data support that roe deer ( capreolus capreolus ) moved into hydropotinae ( presently in which there is only one species : hydropotes intermix ) and stemed its own independent genus ; ( 4 ) the results are object to the usual standpoint that dusky musk deer and alpine musk deer are two different species ; ( 5 ) it is more reasonable that moschidae ( musk deer ) is placed at the level of super family ; ( 6 ) the number of transition within 12s rrna is within the range of 2 to 20 times bigger than that of transversion ; ( 7 ) as to nucleotide composition, adenine ( a ) is much more abundant than any of other bases ( averagely 36. 88 % ) and guanine ( g ) is the least ( averagely 17. 65 % ) in the complete sequence, which is similar with the loop region
（ 4 ）黑麝與馬麝的12srrna基因序列完全相同， 12srrna基因數據不支持黑麝與馬麝為兩個種。 （ 5 ）本實驗結果支持麝作為上科的分類階元存在。 （ 6 ） 12srrna基因的堿基代換中轉換數遠遠大於顛換數（ 2 - 20倍） （ 7 ） 12srrna基因二級結構中，全序列核苷酸的堿基組成腺嘌呤（ a ）最多（平均為36 . 88 ） ，鳥嘌呤最低（平均17 . 65 ） ，與環區的堿基組成相類似。 -
The results showed : ( 1 ) in the d - loop of mtdna genome from 18 individuals, there were only transition and transversion, were not insertion and deletion, and the frequency of transition was higher than transversion ; ( 2 ) and nucleotide diversity was 0. 0011, the sequence divergence values among haplotypes was 0. 005
研究結果顯示： （ 1 ） 18隻大鴇的301bp - 330bpmtdna控制區序列的突變只有轉換和顛換，無插入和缺失，且轉換的頻率高於顛換； （ 2 ）核苷酸多態性只有0 . 0011 ，不同單元型間的序列差異值為0 . 5 。
