种特异性 meaning in English
class specificity
ecies ecificity
species specificity
Examples
- Interferon is almost always host species - specific in function . by contrast , interferon activity is not specific for a given virus ; the replication of a wide variety of virus can be inhibited
干扰素在功能上通常是宿主种特异性。相反，干扰素活性对各种病毒均有效；能广泛抑制各种病毒的复制。 - Sinensis and e . j . hepuensis has been found in the sequences of the portions of 16s rdna and pcr / rflp studies of 110 samples , from six river valleys in eastern mainland of china . these subspecies - specific restriction sites allow rapid discrimination with the endonuclease dra i , and therefore can be used as a diagnostic genetic marker for identification of the two subspecies
通过对中国大陆东部6个水系110个绒螯蟹个体16srdna部分序列的测定和pcr rflp分析，发现在合浦绒螯蟹与中华绒螯蟹之间存在3 4个固定的碱基替代，这种亚摘要种特异性的限制性位点可以通过限制性内切酶dra进行快速检测，成为2个亚种的分子鉴定标记。 - The divergent sequences of rdna from s . costatum are used to design primers meeting the requirements of the rfq - pcr . seven pairs of primers are designed and designated as primer 1 ( f / r ) ~ primer 7 ( f / r ) , respectively , among which primer 1 ( f / r ) , primer 2 ( f / r ) , primer 5 ( f / r ) , primer 6 ( f / r ) showed high level of specificities to s . costatum . then , the pcr products primed by primer6 ( f / r ) are sequenced
首先以中肋骨条藻的rdna序列为设计种特异性引物的靶区域，共设计出7对适合rfq - pcr的引物(依次命名为primer1 ( f r ) primer7 ( f r ) ) ，并用常规pcr实验初步证明其中有4对引物( primer1 ( f r ) 、 primer2 ( f r ) 、 primer5 ( f r ) 、 primer6 ( f r ) )可作为中肋骨条藻特异性引物的候选者；然后测定了以primer6 ( f r )为引物的pcr产物的序列，序列分析表明，中肋骨条藻的pcr产物序列与其他藻的pcr产物序列差别较大，从中可设计出满足rfq - pcr需要的taqman探针(命名为taqman6 ) ；进一步的核酸杂交实验表明， taqman6只与中肋骨条藻的pcr产物杂交，不与其他藻的pcr产物杂交。
