Comments on "linguistic features in eukaryotic genomes"
Tsonis and Tsonis [1] study rank-ordered distributions of the number of occurrences of protein domains in four different organisms, and they argue that the power-law decay, f ϰ 1/r, of the number f of occurrences of a protein domain with its rank r suggests the presence of linguistic features in eukaryotic genomes, and that this finding " may lead to important clues about the evolution of langu...
متن کاملCompositional Features of Eukaryotic Genomes for Checking Predicted Genes
Gene prediction relies on the identification of characteristic features of coding sequences that distinguish them from non-coding DNA. The recent large-scale sequencing of entire genomes from higher eukaryotes, in conjunction with currently used gene prediction algorithms, has provided an abundance of putative genes that can now be analysed for their compositional properties. Strong, systematic...
متن کاملSymbiotic DNA in eukaryotic genomes.
The recent explosive growth of molecular genetic databases has yielded increasingly detailed insights into the evolutionary dynamics of eukaryotic genomes. DNA sequences with the self-encoded ability to transpose and replicate are unexpectedly abundant and widespread in eukaryotic genomes. They seem to be sexual parasites. By dispersing themselves among the chromosomes, they increase their tran...
متن کاملNUMTs in sequenced eukaryotic genomes.
Mitochondrial DNA sequences are frequently transferred to the nucleus giving rise to the so-called nuclear mitochondrial DNA (NUMT). Analysis of 13 eukaryotic species with sequenced mitochondrial and nuclear genomes reveals a large interspecific variation of NUMT number and size. Copy number ranges from none or few copies in Anopheles, Caenorhabditis, Plasmodium, Drosophila, and Fugu to more th...
متن کاملTransposon Occupation in Eukaryotic Genomes
Transposable elements, or transposons, are selfish genetic elements that possess the ability to mobilize within a genome, potentially causing serious damage. They can accomplish this through several well-understood mechanisms. Most move via an RNA intermediate (class I: retrotransposons), whereas others colonize new locations through the direct transfer of transposon DNA (class II: DNA transpos...
