bacs的用法

Average insert size of the library is 118 kb evaluated from analysis of 452 BACs randomly picked from library. So the genome coverage of the library is 13.34 and the possibility to find a single-copy gene in the library is 99.984%.

对随机挑选的452个BAC克隆的插入片段进行鉴定估计文库的平均插入为118kb，文库的基因组覆盖率为13.34倍，预计从文库中筛选到单拷贝基因的机率为99.984%。

The library was screened by using 20 microsatellite markers and 5 known functional genes with PCR. Positive BACs for all these markers and genes were identified successfully and the positive number ranges from 3 to 19 with average of 11.3.

用20个微卫星标记和5个功能基因对整个文库进行PCR筛选，所有这些标记和基因都得到了阳性克隆，克隆数从3到19不等，得到的平均阳性克隆数为11.3。

Laws that establish BACs of0.05g/dl or below are effective at reducing the number of alcohol-related crashes.

将血液酒精浓度设定为0.05克/每分升或者更低的法律，对于减少与酒精相关的撞车数量具有效果。
