Abstract

The spatial distribution of GC content of fragments of the genomes of chloroplasts, mitochondria and bacteria was considered. It was found that the GC content of fragments of most genomes were distributed not chaotically, but in an orderly manner. Two principal types of distribution were found, gradient and centrally symmetric. Chloroplast genomes had only a gradient distribution. Bacteria had a centrally symmetric distribution for GC-poor genomes, and a gradient distribution for GC-rich ones. Both types of distributions occurred in mitochondria; the type of distribution depended on the type of organism.

线粒体、叶绿体和细菌基因组片段空间结构中 GC 含量的分布

对叶绿体、线粒体和细菌基因组片段的 GC 含量的空间分布进行了研究。研究发现，大多数基因组片段的 GC 含量并非无序分布，而是有序分布。发现了两种主要的分布类型，即梯度分布和中心对称分布。叶绿体基因组只有梯度分布。细菌的 GC 贫乏基因组呈中心对称分布，而 GC 丰富的基因组呈梯度分布。两种类型的分布都出现在线粒体中；分布类型取决于生物体的类型。

期刊介绍： Biophysics is a multidisciplinary international peer reviewed journal that covers a wide scope of problems related to the main physical mechanisms of processes taking place at different organization levels in biosystems. It includes structure and dynamics of macromolecules, cells and tissues; the influence of environment; energy transformation and transfer; thermodynamics; biological motility; population dynamics and cell differentiation modeling; biomechanics and tissue rheology; nonlinear phenomena, mathematical and cybernetics modeling of complex systems; and computational biology. The journal publishes short communications devoted and review articles.
