ncbi blast结果中positive 题目:Understanding the Significance of "Positive" Results in NCBI Blast Analysis Introduction: NCBI Blast (Basic Local Alignment Search Tool) is a widely used bioinformatics tool that allows researchers to compare nucleotide orprotein sequences against a vast database. The ...
When BLAST software is used to compare amino acids or DNA sequences with other amino acids or DNA sequences in libraries, similarity searches involve library links to protei 34、n libraries or nucleotide libraries. The link between libraries occurs in the nucleotide database and is linked to ...

The BLAST Sequence Analysis Tool - The NCBI Handbook - NCBI Bookshelf The comparison of nucleotide or protein sequences from the same or different organisms is a very powerful tool in molecular biology. By finding similarities between sequences, scientists can infer the function of newly sequenced...
Bioinformatics analysis of nucleotide sequences of 7 cell culture isolated RSV strains revealed that all analyzed RSV belonged to the RSV-A genotype. Phylogenetic tree of RSV-A sequences showed that, all Sudanese strains were grouped with strains from Belgium and Saudi Arabia. Conclusions: This ...
