Conversely, the relation between the amount of nonprotein-coding dna sequences and organism complexity is more consistent 相對(duì)的,非蛋白質(zhì)編碼序列和生物復(fù)雜程度的關(guān)聯(lián),反而相當(dāng)一致。
Results : designed and synthesized the coding gene of echistatin . and constructe its single copy expression vector, identify the vector by dna sequencing . but it could not express echistatin in e . coli . designed and synthesized the modified coding dna of echistatin, and constructe its two copy expression vector, identify the vector by dna sequencing, but it could not express echistatin in e . coli 結(jié)果設(shè)計(jì)并合成了echistatin編碼基因dna序列,構(gòu)建了echistatin單拷貝表達(dá)載體,經(jīng)dna測(cè)序鑒定正確后,sds-page及western-blotting結(jié)果表明:echistatin在上述菌株中未獲得高效表達(dá)。
