In contrast, the chimp's genes for mesoderm development and skeletal structure had changed more.

相反，黑猩猩的中胚发育基因和骨骼结构基因发生的变化却更多。

With genomic DNA of Clostridium stercorarium as a template, a structural gene pel9A encoding pectate lyase was obtained by PCR amplification. The pel9A was cloned into pET28a to recombine an express plasmid pPel9A, and then the plasmid pPel9A was transformed into E. coli BL-21, expressed under the control of T7lac promoter at 37℃.

利用PCR技术从耐热梭状芽孢杆菌中扩增得到产耐热果胶裂解酶的结构基因pel9A，并将其克隆于表达载体pET28a中，最后将此重组质粒转化到受体菌E.coli BL-21中进行表达。

The structure gene pelA from Thermotoga maritima MSB8 encoding pectate lyase was amplified and ligated into pHsh, resulting pHsh-pelA. Through structural optimization on pHsh-pelA, the ultimate plasmid, pHsh-pelC, which possessed the most appropriate structure and free energy of mRNA, was obtained.

将来源于极端嗜热菌属海栖热袍杆菌Thermotoga maritima MSB8的编码碱性果胶裂解酶的结构基因pelA与新型热激质粒pHsh连接，得到重组质粒pHsh-pelA，运用mRNA二级结构预测软件对pHsh-pelA的翻译起始区的二级结构进行优化，得到了具有最佳mRNA二级结构及自由能的质粒pHsh-pelC。
