BLAST use a partial algorithm to find the similar sequences between two sequences. There are some common used program in the BLAST : BLASTP, BLASTX, BLASTN, TBASTN, TBLASTX. Today, BLAST and FASTA is two of the most popular comparing program, which is widely used in the biology field....
点击右边的“Links”，再点击里面的“Related Sequences”就能找到所有的大鼠c-jun mRNA序列及其他物种 ...
使用新版BLAST验证引物特异性 同时输入上下游引物。输入上下游引物系列都从5撇到3撇。输入上游引物后，加上20个字母n，再输入下游引物 再进行参数设置 点击BLAST进行搜索。两线段间有连线的代表这些序列与上游引物匹配、并与下游引物互补理论上可以扩增出基因片断。没有连线的，表示单条引物与该基因一致。

Blat is an alignment tool like BLAST, but it is structured differently. Blat produces two major classes of alignments: at the DNA level between two sequences that are of 95% or greater identity, but which may include large inserts.

An exact solution to the global alignment problem was developed by Saul Needleman and Christian Wunsch in 1970, by applying dynamic programming to find the optimal alignment between two sequences. In 1981, Temple Smith and Michael Waterman extended this dynamic programming approach to solve the...
Sequence alignment betweentwosequences Find anoptimalalignment between two sequences 3 Dynamic programming 动态规划(英语:Dynamic programming,简称DP)是一种在数学、管理科学、计算机科学、经济学和生物信息学中使用的,通过把原问题分解为相对简单的子问题的方式求解复杂问题的方法。
