颠换 meaning in Chinese
[生物学] traser; transversion
Examples
- The substitution of a purine for a pyrimidine, or vice versa is a transversion .
嘌呤为嘧啶取代或嘧啶为嘌呤所取代，叫做颠换。 - Transversion has the bias of a t and t a , and always happen in the 3rd position
颠换的发生主要以t - a ， a - t为主，大都发生在密码子第三位。 - Among the nucleotides substitution of cytb , transition is obviously higher than transversion
斑翅蝗cytb基因中核苷酸的替代转换明显高于颠换。 - ( 8 ) the substitution rate in loop regions is 2 . 24 times of that in stem regions . the transition rate is almost same ( 0 . 051 and 0 . 082 ) , compared with the results that the transversion rate of loop regions is the 12 . 67 times of that of stem regions
( 8 )环区的所有核苷酸碱基代换率为茎区的2 . 24倍，转换率几乎相同( 0 . 051和0 . 082 ) ；而环区的颠换率却高达茎区的12 . 67倍。 - At the same time , there exists not some base deletion but only base substitution among them . there are 6 base transitions between the sequence of boacal5 ' and boccal5 " , and 2 transitions and 1 base transversions between boacal5 " and bogcal5 " , 3 transversions and 2 transitions between boccal5 " and bogcal5 " . 3 . alignment of according sequences of putative amino acid of cal homologs from 8 plants reveals high conservation according to the mads domains of them
发现三者之间碱基序列差异仅仅是发生了碱基替代而不存在碱基的缺失现象，其中boacal5 ’与boccal5 ’之间存在6次碱基转换，而boaca15 ’和bogcal5 ’之间则存在2次碱基转换和1次碱基颠换， boccal5 ’和bogcal5 ’之间则有3次碱基颠换和2次碱基转换。
