Sentence examples for molecular evolutionary change from inspiring English sources

Furthermore, students have the opportunity to witness molecular evolutionary change.

Random genetic drift was not only important; it was the chief force governing molecular evolutionary change.

This viewpoint is intellectually pernicious because it blinds researchers to the processes that actually drive molecular evolutionary change and to well-established consequences of gene-level selection, such as genomic conflicts, that mediate a substantial proportion of human disease risk.

Comparative analyses of the closely related species can provide this type of information concerning a possible evolutionary change in functional signal sequences such as TFB motif sequences, but the addition of the computer-generated ransom sequences cannot provide the information concerning the molecular evolutionary change.

This finding supports the hypothesis that ecological factors affect molecular evolutionary changes in mammalian V1R gene family size.

Here, genomics analyses of isolates from this rapidly expanding clonal population offered an opportunity to observe the molecular evolutionary changes often obscured in more diverse populations.

In general, while receptor conversion can occur because of true molecular evolutionary changes associated with tumor progression, it can also be due to the inherent subjective nature of immunohistochemical evaluation.

Regardless of the mechanistic explanation, one key result from our study was that molecular evolutionary changes were rather modest after 350 viral generations (sum total of 2750 generations, adding together the generations occurring on all of the branches in the tree; Figure 1); clones isolated at the tree tips sometimes contained only 4 substitutions separating them from the wildtype ancestor.

Our finding that positive selection was especially prominent along the primate-origin lineage suggests that molecular-evolutionary changes underlying important features of complex social cognition were established well before separation of the human lineage.

Because antibiotics influence the natural stability of the units within the hierarchy (above), they can leave up-down and down-up molecular traces of evolutionary change, which are detectable via bioinformatics analyses (Bapteste et al. 2012).

Further study of mechanisms governing the adaptive changes responsible for high-altitude adaptation will contribute to our understanding of the molecular basis of evolutionary change and assist in the functional annotation of the human genome.
