直接测序法 meaning in Chinese

direct sequencing

Then , to get more knowledge about the rpob gene mutations and provide some scientific information to study the molecule mechanism of resistance to rifampin in mycobacterium tuberculosis , the rpob gene sequence of mycobacterium tuberculosis clinical isolates from shannxi was analysed by direct sequencing of pcr products
随后通过直接测序法对陕西区域内结核分枝杆菌临床分离株rpob基因pcr扩增产物进行序列分析，了解该区域rpob基因突变情况，为研究结核分枝杆菌耐利福平的分子机制提供参考。
