mutational change

Their global atom war only happened 8 years ago; there hasn't been enough time yet for development of mutational changes.

But others, like its human species, were subjected to a progressive degeneration by the mutational changes.

The argument that a mutational change would make the avian flu virus a much greater threat is seriously flawed.

However markers showing adaptive responses to environmental change can be 'non-neutral' (e.g. mutational changes affect their relative fitness within a population).

Most of these changes are monitored using 'neutral' genetic markers (markers for which mutational changes do not change their adaptive fitness within a population).

Isolates are divided into phage types, but some phage types do not have a single origin as determined using mutational changes.

Remember that, however complicated the embryological status quo may be in any given generation, each mutational change in the status quo can be very small and simple.

The associated subtype changes each year, due to development of immunological resistance to a previous year's strain (through exposure and vaccinations), and mutational changes in previously dormant viruses strains.

In a Nature study published in 2011, Ding et al. identified cellular fractions characterized by common mutational changes to illustrate the heterogeneity of a particular tumor pre- and post-treatment vs. normal blood in one individual.

In the absence of a direct assay for sterolin-1 and -2 function, the genetic changes presented, together with the correlation of the phenotypes, remains the strongest evidence that these genetic alterations are functional, and that the Gly583Cys is a mutational change.

With the amount of research conducted on cancer genomes and the accumulation of databases documenting the mutational changes, it has been predicted that the most important cancer-causing mutations, rearrangements, and altered expression levels will be cataloged and well characterized within the next decade.

Through analyzing the same genes in many different species and tracking how many mutational changes have occurred in the genes from one organism to the next, scientists are able to calculate kinships based on complex mathematical models rather than on an eyeball appraisal of how species look.
