摘要
序列比较的基本任务有:(1)对于两条长度相近的序列相似,找出序列的差别;(2)判断一条序列的前缀与另一条序列的后缀相似;(3)判断一条序列是否是另一条序列的子序列;(4)判断两条序列中是否有非常相似的子序列。对核苷酸二联体给出DNA序列一种编码规则,利用异或操作进行序列比较。
quences; （2） The basic task of the sequence comparison is ： （ 1 ） to distinguishing the difference between two seto judge the prefix of a sequence matches the suffix of the other sequence; （3） to judge two sequences have common subsequences; （4） to judge a sequence is the subsequence of another sequence. A coding method is proposed based on dual nucleotides of the DNA sequence and made sequence comparison based on exclusive-or operation.
