细菌和古细菌全基因组中的周期相关结构

Periodic correlation structures in bacterial and archaeal complete genomes

Zuo-Bing Wu

摘要:

利用度量表示和递归图方法研究了细菌和古细菌全基因组中核苷酸串的周期迁移。产生的周期关联结构具有四种基本的传输特性:单增周期、多增周期、准增周期和几乎无增周期。通过确定细菌和古细菌完整基因组中所有长周期核苷酸串,进一步分析了周期转移的机制,解释为:基本周期核苷酸串的重复和非周期核苷酸串的转移都会形成增加周期大致相同的周期相关结构。

英文摘要:

The periodic transference of nucleotide strings in bacterial and archaeal complete genomes is investigated by using the metric representation and the recurrence plot method. The generated periodic correlation structures exhibit four kinds of fundamental transferring characteristics: a single increasing period, several increasing periods, an increasing quasi-period and almost noincreasing period. The mechanism of the periodic transference is further analyzed by determining all long periodic nucleotide strings in the bacterial and archaeal complete genomes and is explained as follows: both the repetition of basic periodic nucleotide strings and the transference of non-periodic nucleotide strings would form the periodic correlation structures with approximately the same increasing periods.
