Codon usage bias (CUB), the uneven use of synonymous codons, is a ubiquitous observation in virtually all organisms examined.
The primary factor was polarized, such that values correlated positively with Chi/L (Shields et al. 1988) and negatively with effective number of codons (Wright 1990); both are measures of uneven codon usage, with Chi/L increasing and ENC decreasing as codon usage becomes less even.
Unfortunately there is still an uneven distribution of PACS throughout Europe, which leads to significant differences between countries regarding the usage of teleradiology.
It must also be taken into consideration that further protection could be provided by uneven codon usage, i.e. in case of multiple codons for one amino acid those codons are preferred that are dissimilar to codons that code for dissimilar amino acids.
Usage of chlorine skyrocketed.
Note my usage of the plural, surveys.
That is entirely constructive usage of technology.
No other usage of integrity here applies.
"The usage that's coming is the usage of its time".
Usage of "end" is also often ambiguous.
