However, by RNA dot hybridization the amount of mRNA produced in the transcription of parg-leuS was about 5 times that of the wild type le uS, and was similar to that of pKK-leuS, suggesting that the promoter of argS is very strong.

• 但是 ,RNA斑点杂交却发现从 parg leuS转录出来的leuSmRNA是野生型leuS转录的 5倍 ,几乎与从 pKK leuS中转录出来的量差不多 ,说明argS的启动子很强 ,接近于trp lac。
