病毒基因组中的对称性(英文)

Symmetrical sequence in virus

病毒基因组中的重复序列比率很低,因为其核酸序列大都是编码区域.如果出现一段同向对称或者是反向对称序列在病毒基因组中,它往往代表一个调控元件,或者是一个信号因子.我们总结了病毒中的一些对称序列,并阐明它的特点,分布及功能.

There is a small scale repeat sequences in virus genome, because much of prokaryotic nucleotides are encoding sequences. If there occur a repeat or inverted phase in prokaryotic genome, probably it represents a notable symbol： either it is a regulated element, or a stable signal. Here we generalize some kinds of repeat sequences in viruses, include its property, distribution and function.
