Sentence examples for dna composition of a from inspiring English sources
We have created a way to depict the DNA composition of a given sequence for visually inspecting the presence of compositional transitions.
Thus, genomic homogeneity, as measured using Markov chain based genomic signatures, is positively correlated with bias in genomic tetranucleotide patterns in the sense that the less random walk like the DNA composition of a genome is, the more homogeneous the genome is.
We claim that the mutational pressure leading to the nucleotide substitutions is extremely highly correlated with the DNA composition of the genome in such a way that the higher substitution turnover of a nucleotide determines the lower fraction of this nucleotide in the DNA sequence.
An explanation may be that the genomic DNA composition of prokaryotes is more sensitive to changes in conditions affecting mononucleotide frequencies than phyla.
These observations suggest that the sequence organization and DNA composition of PCEN regions are important to centromere function.
The DNA composition of band #4 of the Percoll density gradient was also characterized by PCR, after extracting the DNA from an aliquot using phenol-chloroform.
The dramatically different DNA composition of proximal promoters in mammals [ 1] compared to yeast [ 2] and Drosophila [ 3] suggests that different mechanisms regulate gene expression in those organisms.
We agree that if hypothetical 15mer (or shorter) human DNA composition of matter claims were routinely granted, this would be extremely problematic because they might cover a large percentage of genes.
Amelioration is the process by which the DNA composition of the newly acquired gene becomes homogenized to match the composition of the recipient genome (all genes in the recipient genome are subject to the same mutational processes) (Lawrence and Ochman, 1997).
The resulting tree reflects the similarities between the DNA compositions of the ORFs in the contig.
Consistently, after factoring out the influences of underlying DNA composition and of phylogenetic inertia from the AAC, it becomes considerably less predictive of the environmental preferences.
