Sentence examples for excess of changes from inspiring English sources

This modification by using this condition led to an excess of changes from Adenine to Guanine) and (Thymine to Cytosine), which had been a significant impact on the error rate (Sinha and Haimes 1981).The frequency of mutation in Ep-PCR could be changed by adjusting PCR conditions that provided accessibility in operation for evolution experiments (Wang et al. 2006).

To explore the physiological effects of copper (Cu) excess on changes in Lycopersicum esculentum plant growth parameters, lignin accumulation, malondialdehyde (MDA) content, mineral homeostasis, and antioxidant enzyme activities were studied in seedlings grown in nutrient solution supplemented with CuSO4 −induced oxidative stress.

The excess of small changes may be due to selection against extreme changes in gene length, whereas the excess of longer changes is intriguing and could be due to nonrandom distribution of stop codons in some 3′ untranslated regions.

The absence of parallel changes in the terminal branches is consistent with the excess of parallel changes in deep branches of phylogenetic trees described above.

Although the observed excess of parallel changes in internal branches gained unequivocal statistical support, the raw numbers of parallel changes were small.

The deviation from randomness is presence of a small excess of base changes closer than predicted, which are presumably due to clustered mutations, as identified by Drake [64].

The excess of parallel changes in deep branches of phylogenetic trees is a notable evolutionary phenomenon in itself.

In particular, the intriguing finding of a dramatic excess of parallel changes in internal branches of a phylogenetic tree compared to terminal branches (leaves) begs an explanation.

In a broader evolutionary context, the observed excess of parallel changes seems to provide the molecular-evolutionary underpinning for the "law of homologous series in variation".

The results of early reports are conflicting, but there is some evidence for an excess of premalignant changes, particularly for BRCA2 mutation carriers [ 32- 34].

The excess of parallel changes for distantly related species observed in this paper reverberates with the recent finding of a high frequency of parallel changes in evolving protein sequences from mammalian, fruit fly and yeast species [ 48].
