A more trivial artifact may result from cross-hybridization with mRNA, which certainly could be the case for the probes for non-human miRNAs that make up a disproportionate fraction (67%) of this group.
However, cloning and sequencing artifacts may result in a large number of genuine miRNA sequences that deviate from this expected range.
Global monitoring can occur from a single satellite as it orbits the earth, minimizing artifacts that may result from regional differences in ground-level network design and operation.
Because such regulatory proteins can be present at different levels and in different molecular complexes in nuclei as compared with the cytoplasm, separation of the two cellular compartments allowed an assessment of the site(s) at which these proteins exert their primary activity unimpeded by artifacts that may result from intermixing the two compartments.
Bias and artifacts in neuroimaging signals may result from imaging systems, environment, and body motion.
Although many of these may represent true genomic duplications it is also possible that some may result from artifacts in the current draft genome assembly.
This suggests that this topology is prevalent among genes carrying the highest levels of phylogenetic signal, and that a significant fraction of the alternative topologies may result from artifacts.
The fact that a highly non-random enrichment of such epigenetic markers with the PR was detected by super-resolved microscopy based on different physical principles rules out that our findings may result from artifacts of the complex algorithms involved in 3D-SIM generated images.
Since most of the other chelicerates and N. gracile have strand-biased nucleotide contents [ 44]as well as extremely long branches on the phylogenetic tree (Fig. 6), the possibility remains that the appearance of Pycnogonida within Arachnida may result from artifacts of analysis due to the strand-biased and long-branching patterns.
The reconstructions display significantly different intensities for the two sources, which may result from measurement artifacts or inadequate prior knowledge of the optical properties of the phantom material.
Inability to detect TSS expression may result from technical artifacts such as low expression levels not discernible at the conducted depth of sequencing or the use of an alternate tissue specific start site.
