For the first time in history we can track the evolution of a pandemic in real time. Influenza viruses are notorious for their rapid mutation and unpredictable behaviour.
Quotes about mutation (16 Quotes)
It's that mutation that causes an enhanced aggressiveness of the virus. It's a nastier and meaner virus than the abortion strain, has a higher mortality rate (and) spreads more rapidly.
A comparison between the triplets tentatively deduced by these methods with the changes in amino acid sequence produced by mutation shows a fair measure of agreement.
It could reduce the mutation level... you are less likely to have widespread mutation than if you had 20 strains hop-scotching across Asia. Surveillance and response of H5N1 in both animals and humans needs to be strengthened in all regions bordering countries where outbreaks have been identified.
But the point is that Christ's resurrection is something more, something different. If we may borrow the language of the theory of evolution, it is the greatest 'mutation,' absolutely the most crucial leap into a totally new dimension that there has ever been in the long history of life and its development a leap into a completely new order which does concern us, and concerns the whole of history.
In microbiology the roles of mutation and selection in evolution are coming to be better understood through the use of bacterial cultures of mutant strains.
What we can learn from historical plant domestication will benefit our ongoing and future effort to domesticate energy crops that will be equally important to the long-term sustainability of our society. It is remarkable how the earliest farmers could have selected a single mutation in DNA to develop a major food crop of the world.
We forecast that bird flu mutation is possible in the countries where the number of different viruses is high. This group includes the United States.
The more these viruses interact with the human population, the more likely it is that it could adopt this type of mutation.
Attempts have been made from a study of the changes produced by mutation to obtain the relative order of the bases within various triplets, but my own view is that these are premature until there is more extensive and more reliable data on the composition of the triplets.
The common polymorphism alone does not cause SIDS. Our findings suggest, however, that it renders infants vulnerable to environmental challenges -- such as a long pause in respiration -- that are tolerated by children without the mutation.
The virus would hit this mutant cell and cause a second mutation, prompting the onset of cancers like leukemia or brain tumors.
There is nothing exempt from the peril of mutation the earth, heavens, and whole world is thereunto subject.
That the primary effect of gene mutation may be as simple as the substitution of a single amino acid by another and may lead to profound secondary changes in protein structure and properties has recently been strongly indicated by the work of Ingram on hemoglobin.
Although I insist that God has always had the power to intervene directly in nature to create new forms, I am willing to be per-suaded that He chose not to do so and instead employed secondary natural causes like random mutation and natural selection.
The balance of evidence both from the cell-free system and from the study of mutation, suggests that this does not occur at random, and that triplets coding the same amino acid may well be rather similar.
