Sentence examples for mutations over a from inspiring English sources

Can random mutations over a mere 3.8 billion years really be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of nature's creative marvels?

Cancer is usually caused by the accumulation of mutations over a lifetime.

In the CF lung, however, the colonizing P. aeruginosa clone will diversify in morphotype and lifestyle concurrently with airway remodelling and dedifferentiation [3] and sequentially accumulates mutations over a period of months to decades [8], [30], [31].

By using labeled dideoxynucleotides in our primer extension and replicate arrays, we were able to identify mutations over a 2643 nucleotide region without a priori knowledge of specific polymorphisms.

Although some mutations are homozygous viable, and therefore did not require the use of a balancer chromosome to maintain the mutation in a w− background stock, all stocks were selected to maintain the mutations over a balancer chromosome, and these were employed for analysis.

These aberrant empty sites are often the only mutations over a long stretch of flanking sequences (up to 1 kb), suggesting that they may have resulted from the transposition activity of ATons.

Research has been focused on the findings of possible driving genes of this disease, especially those genes with high frequent mutations, over-expressions, or fusions for a long time.

The point of every chapter – every page in fact – is to convince the reader that what we see now, buzzing, flapping or scuttling around us everywhere, is the consequence of the operation of natural selection upon random mutations over an immense period of time.

We choose this approach to introduce new deleterious mutations over an approach that assumes that infected individuals can 'mutate' from being infected with a virus having a specified number of deleterious mutations to being infected with a virus having a higher number of deleterious mutations.

This result shows that orientation with respect to the replication fork can have an impact on mutation rate for a single base-pair substitution; however, this is unlikely to impact mutation rates in our experiment because we are detecting loss-of-function mutations over an entire gene, which will average out these small-scale effects.

Therefore it will be difficult to group sequences that have shared similar regimes of NBDM mutation over a given period of interest with the goal of gathering from them enough substitutions for parameter estimation.
