head-tail sequence
解釋
頭尾順序-
Some tendency of tn5gusa5 transposition were found that all preferred sites of tn5gusa5 in xcc 8004 genomic dna are in at - rich regions ; target sequences of tn5gusa5 have some features that the probabilities of guanine and cytosine are high respectively at the head and tail base of target sequence ; the level of gene transcription does not influence insertion density of tn5gusa5 significantly
結果表明, tn5gusa5插入位點有一定的規律性: tn5gusa5在xcc8004基因組上傾向于插入低gc含量( 50左右的區域插入密度最高)區段;插入位點的靶序列有一定的特異性,在靶序列的首位鳥嘌呤出現的幾率高,而在靶序列的末位胞嘧啶出現幾率高; tn5gusa5的插入密度與該區段基因的轉錄水平無明顯關系。 -
Furthermore, the sequences were analyzed and compared with the sequence data in genbank. the results indicated that the cyanophage represented a phage - like shape with head diameter ca. 47 - 52nm and a short tail almost invisible
研究結果表明:此病毒在負染電鏡下為噬菌體形態,頭部直徑約47 - 52nm ,尾部幾乎不可見。
