So, here are 20 words which we can say, with some certainty, originated in works of literature.
Based on these data, we cannot determine with certainty where the haplotype originated from, but we can assume it had a relatively more recent origin than the other two haplotypes (A and B) and dispersed only through the western region.
This history is very complicated, so it is hard to say with certainty where the archaeal enzymes originated.
Thus, the likelihood of two or more GFP+ PRPs adhering to each other in these culture conditions are highly improbable and, therefore, we can report with almost certainty that each GFP+ cluster originated from one GFP+ cell.
For others, elevator phobia originates in the chilling certainty that the frayed shoelace on which the car is suspended will snap.
The four mitochondrial lineages common among Ashkenazis are now very rare elsewhere in the Near East and Europe, making it hard to identify with certainty the lineages from which they originated.
Surprisingly, the vast majority of duplications (60%) involve two different Muller elements (i.e., indicating relocation of the duplicated gene), and a high percentage (39%) could be concluded to have originated by retroposition with certainty (table 1).
Diagnostic PCR and in situ hybridization confirmed with certainty that the 16S rRNA gene sequences originate from the symbiotic bacteria in the isolated cavity of the midgut crypts.
However, it can with greater certainty be concluded from where the haplogroups did not originate.
In PC, which occurs commonly multifocal, it is not known with absolute certainty from which part of the organ the metastatic spread originates.
