Elementary networks are defined by the condition that a specific chemical conversion can be performed by a set of given reactions and that this ability will be lost by elimination of any of these reactions.
The lack of MATα sequences in the genome of ATCC10895 and the 100% sequence identity distal to the MAT loci in the sub-telomeric regions of chromosome IV and chromosome VI suggests that the MATα genes together with the distal portion of chromosome VI were lost by a gene conversion event as indicated in Figure 5A.
Since all practical conductor materials are characterized by some electrical resistance, part of the electric current is always lost by conversion to heat, which is radiated from the wire.
In a proton-proton cycle, four hydrogen nuclei (protons) are combined to form one helium nucleus; 0.7 percent of the original mass is lost mainly by conversion into heat energy, but some energy escapes in the form of neutrinos.
Copy number influences the level of expression, and copies can be lost in subsequent generations by gene conversion.
The signal-to-noise ratio for the product, SP-B(1 25) + 3O, was much lower than for the starting material, SP-B(1 25); hence, Kim et al. suggest that the oxidized form of SP-B(1 25) may be lost entirely from the interface, rationalized by the conversion of fairly hydrophobic residues into more hydrophilic species.
However, when one-way conversion is insufficiently counterbalanced by selection, the original cell type will ultimately be lost, often with negative impacts on the population's overall fitness.
However, DNA sites that activate recombination hotspots are removed preferentially by gene conversion when heterozygous (Gutz 1971; Schuchert et al. 1991) and hence should be lost from the genome over successive generations.
As a consequence, we can no longer answer queries for the phenomena represented by SBML's Reaction model elements since we use universal quantification in their formalization (see Methods section) and these axioms are lost after conversion to OWL EL.
