By using four methods (histogram, chaos game representation, discrepancy of distance and discrepancy of entropy) at genomic level, the composition of short oligonucleotides and their compositional complexities in three different regions(introns, intergenic DNAs and exons) of genomic DNA from Arabidopsis thaliana, Caenorhabditis elegans and Drosophila melanogaster were studied. It can be concluded that: (1) although the genome sizes and gene numbers are quite different, the compositional complexities of exons are similar, while that of noncoding regions are quite different between eukaryotic genomes. From quantitative perspective, this finding means that the degree of organismal complexity is mainly reflected by noncoding regions, but not by exons; (2) in the same regions of genomic DNAs, composition and compositional complexity are highly similar between chromosomes or contigs within eukaryotic genomes; (3) composition differ remarkably little between introns and intergenic DNAs. This suggests that the effects of transcription, splicing, second structure contribute minimally to the constraints operating on these sequences.

在全基因组水平上 ,用直方图、混沌表示灰度图、距离差异度和信息熵差异度四种方法 ,研究了拟南芥、线虫、果蝇的DNA内含子、基因间隔区DNA、外显子三种区域的核苷酸短序列组分及组分复杂度 .结果表明 :a 不同基因组之间 ,不管基因数目多少 ,用 4种方法得到的外显子部分其组分复杂度都比较接近 ,而非编码区部分的组分复杂度却很大 .这一点定量地说明了物种之间的复杂程度 ,主要不体现在编码区部分 ,而体现在非编码区部分 .b 同一基因组中 ,内含子的核苷酸短序列组分复杂度都是相似的 ,外显子和intergenicDNA部分的组分复杂度也是相似的 .c 内含子和intergenicDNA在转录、剪切、二级结构等方面有很大的不同 ,但它们在核苷酸短序列组分上的差异却很小 ,说明内含子和intergenicDNA在转录、剪切、二级结构上的不同并不通过核苷酸短序列组分来进行限制 .
