The feature sequences of coding region and noncoding region can be determined based on the a, then we can express the dna sequences to feature vectors 在此基礎(chǔ)上給出了dna序列的特征向量表示,并用修改前后的svm分類器進(jìn)行分類。
For the svm classifier, we use the complete sequence of arabidopsis thaliana to research the coding region and the noncoding region in dna sequences 對svm采用了擬南芥全序列數(shù)據(jù),對序列中的編碼區(qū)序列和非編碼區(qū)序列進(jìn)行了研究。
Meanwhile, base composition in rrna genes, the secondary structrues of trna and the potential stem-loop structure in the noncoding region were also analysesed in the present study 同時(shí)分析了d1na基因的堿基組成、trna的二級結(jié)構(gòu)、非編碼區(qū)潛在的莖環(huán)結(jié)構(gòu)。
The cloned segment a contains 3259 nucleotides in full-length and includes two partially overlapping open reading fragments ( orf1 and orf2 ) flanked by 5 " and 3 " noncoding regions ( ncr ) . the two strains shared high sequence homology with each other either at nucleotide or deduced amino acid level 序列測定結(jié)果表明,兩株病毒的基因組a節(jié)段全長共3259個(gè)核苷酸,包括5’、3’端的非編碼區(qū)(ncr)和兩個(gè)部分重疊的開放閱讀框(orf1和orf2)。
