摘要:
以E.coli JM83染色体DNA为模板PCR扩增ubiA的结构基因,将PCR产物克隆于pUCm-T Vector,对PCR产物进行测序鉴定.与已发表的大肠杆菌ubiA基因序列比较,同源性达99%.

Cloning and Analysis of DNA Sequence of Gene ubiA of E.coli
Abstract:
A DNA fragment was amplified from the chromosomal DNA of E. coli JM83 by PCR and then was cloned into pUCm - T vector. The cloned fragment was sequenced. Comparing the DNA sequence of the amplified fragment with the published sequence of gene ubiA. showed that they were 99% homologous.
