聚腺苷酸化 meaning in Chinese

polyadenylation

But polyadenylation in bacteria needs no specific consensus sequence or there is no such sequence signals found . the sites of polyadenylation of bacterial mrna are diverse , including the 3 ' ends of primary transcripts , the sites of endonucleolytic processing in the 3 ' untranslatd and intercistronic regions , and sites within the coding regions of mrna degradation products
细菌mrna多聚腺苷酸化的位点多种多样，包括初级转录产物的3 ’末端， 3 ’端非翻译区和顺反子间区的内切酶加工位点及mrna降解产物的编码区内，其腺苷酸化相对无特异性、无选择性。
It has been known that polyadenylation of 3 " end of mrna in prokaryotes is different from that of eukaryotes . the poly ( a ) tracts in bacteria are generally short , ranging from 15 - 60 adenylates residues and associated with only 2 - 60 % of the molecule of a given mrna species . mrna polyadenylation of eukaryotes always occurs in the untranslated region , 10 - 30 nucleotides downstream of the hexanucleotide sequence aauaaa
现在普遍认为细菌许多mrna3 ’端存在多聚腺苷酸尾，但其长度通常较短，大约在15 - 60腺苷酸残基范围，且对某一mrna而言，仅有2 - 60的分子被多聚腺苷酸化。
