Cloning of UGPase is a premise for further study on molecular level, and it is also crucial for study of carbohydrate metabolism. UGPase cDNA sequence as a template, designed primer, then 3＇-untranslate region （3＇ UTR） of UGPase were amplified by 3＇-rapid amplification of cDNA ends （3＇-RACE）. The results suggested the 3＇ UTR were 243 bp, contained AATAA sequence and Poly（A）.展开更多
