When analyzing genes in the largest plasmid, for the first time it is found that the strand-specific mutational biases are responsible for the primary variation of codon usages in plasmid.
This study characterises the primary structural variation in the coding sequences of the AOP2 gene and identifies three different AOP2 alleles based on polymorphisms in exon two.
Measures of primary sequence variation in ribosomal RNA, ribosomal protein, and non-ribosomal enzyme protein show that the corresponding gene sequences provide a record of natural variation associated with phylogeny in bacteria and archaea [ 1, 2].
Europe-wide application of the PC Monitor is expected to result in up-to-date information on the structure, process and outcome of primary care systems, variation in primary care systems across Europe and knowledge about primary care oriented policy strategies (e.g. related to accessibility or integration).
Although we put a considerable effort on creating cohorts from claims data based on date of birth, age, and place to closely resemble cohorts from primary sources, variations in the compositions of the compared cohorts may have implications on the estimated VC.
Multilevel principal component analysis was used to investigate the primary sources of variation in serum metabolic profiles of subjects from the discovery cohort, using the 35 metabolites measured.
Thus, besides polyploidization, LTR-RTs can be the primary candidates for variation in genome sizes, owing to their differential rates of proliferation in different species (Fig. 8).
The differences to our results could be caused by the use of different primary antibodies or variation in cell counting methods.
Germination is the most critical stage in the life cycle of many plants and is the primary source of variation in the regeneration niche.
However, because group size increased with food quality and quantity, food resources emerged as the primary driver of variation in behavioural strategies.
