Tandem repeat is a kind of repeat which consists of two or more continuous copies 串联重复序列就是重复单元首尾相连,串接在一起的重复序列。
The length of the polymer chain is specified by the number of repeat units in the chain . this is called the degree of polymerization 聚合物链的长度可以用链中重复单元数来表示,叫做聚合度。
Repetitive sequences make up a significant fraction of genomes . according to the way they are arranged , repetitive sequences can be generally classified into two large groups : tandem repeat and dispersed repeat 重复序列在基因组中广泛存在,按照重复单元的排列方式,可将它分为串联重复序列和散在重复序列两大类。
