Sentence examples for molecular evolution patterns from inspiring English sources

Different molecular evolution patterns may be related with distinct selective constraints acting on different species.

The influence of both population size and recombination level, most likely, leads to the differences in the molecular evolution patterns of endosymbiotic and free-living bacteria [ 16- 18] and to degeneration of the neo-Y chromosome of Drosophila miranda [ 19].

Quartet sequences (two paralogous genes from two different species) were used to detect the molecular evolution pattern under gene conversion.

Therefore, more pathways with different topologies are needed to disentangle the underlying evolutionary forces that affect the molecular evolution pattern of the elements in pathways [ 15].

However, it has been impossible to relate the presence of two subtypes of mRNA which differ by their 5' UTR region and the great number of paralogs in a coherent molecular evolution pattern.

With the resulting transcripts, we (1) characterized the sequence divergence between the two closely related stickleback species, (2) investigated rates of molecular evolution for patterns consistent with positive selection, and (3) evaluated sequence differentiation between marine and freshwater nine-spined sticklebacks.

While a comparison between the venom-gland transcriptomes of the two venom types in C. horridus might have provided a more precise comparison of expression patterns underlying the two venom types, such a comparison would provide substantially less data on toxin and nontoxin molecular evolution and on patterns of gene-family evolution in snake venoms.

The molecular evolution and transmission patterns of rabies virus inferred from historical data can provide guidelines for better disease control and prevention in the future.

Thus, a basal radiation of the Procellariiformes in the Eocene at least (as with many modern orders of birds) seems likely, especially given that significant anomalies in molecular evolution rates and patterns have been discovered in the entire family (see also Leach's storm petrel), and molecular dates must be considered extremely tentative.

To address these questions, we used our annotated nontoxin sequences from C. adamanteus and C. horridus as the basis for our null expectation for molecular evolution and compared the patterns for toxins to the patterns for nontoxins.

These observations have called into question a very basic assumption of molecular evolution; that naturally occurring patterns of molecular variation in noncoding regions accurately reflect the underlying processes of randomly accumulating neutral mutation in nuclear genomes.
