Sentence examples for rate of origin from inspiring English sources

These results suggest a mechanism by which PP2A levels control the rate of origin firing in Xenopus egg extracts and in Xenopus embryos at the MBT.

Specifically, the population of origin and destination country, the infant mortality rate of origin and destination, the distance between capitals and the land area of the destination display a significant and substantial impact on immigration activities.

The trend is obvious in the fossil record, but documenting it using a high-resolution hierarchy scale reveals three puzzles: 1) the rate of origin of new levels accelerates, at least until the early Phanerozoic; 2) after that, the trend may slow or even stop; and 3) levels may sometimes arise out of order.

In addition to the catching-up process, Equation (1) relates the change in institutional quality to the past values of the emigration rate of origin country i (m it-1 ) the past level of institutional quality in the host country (denoted N it-1 ) and the past level of human capital in country i (H it-1 ).

The distribution of such fluctuations depends, among other parameters, on the time-dependent rate of origin usage [15], [16].

Once again, the rate of origin activation increases during the first half of S phase then decreases sharply before the end of S phase.

Assuming this is also the case in S. pombe, we have divided the S phase time frame of Eshaghi et al. by a factor of 3 and translated it by 70 min so as to match the S phase start and end times of Heichinger et al. Figure 1C shows that when the data are plotted this way, the time-dependent rates of origin firing determined from both experiments indeed coincide.

Second, we determined the regions along the chromosomes where estimated rates of origin firing were the highest.

Due to the high rates of origin of spontaneous duplications and deletions, copy-number changes containing the same genes arose readily in independent populations.

Given the role of gene duplication in the emergence of evolutionary novelties and their high spontaneous rates of origin, human-specific gene duplicates would appear to be a promising avenue for investigation.

This is not contradicted by the fact that Amazon molly triploids can be observed in the wild [ 23], as strong purifying selection would predict vanishing frequencies, since the rates of origin of triploids are rather low in this fish [ 23].
