There are several candidates, including a dementia mutation discovered just three months ago, by the Mayo Clinic's Hutton.
In the most recent film version of "I Am Legend" (a 1954 story by Richard Matheson), the zombie-like mutants are the result of an attempt to cure cancer.
However, most mutations are deleterious.
Viruses can also cause genetic mutations when they integrate themselves into human DNA.
But now in some cases we choose to keep these bad mutations around.
Those mutations had little effect on how the receptor grabbed hormones.
But the prevailing view has long been that cancer is the result of genetic mutations.
Most of these mutations are known as "passengers" and cause damage but not cancer.
However, these minor "mutations" cannot change what the virus does, only what it looks like.
There they were: signal noise, mutations, executive function, self-organization.
They look at mutations as kind of a random event.
Mutations are the driving force of evolution.
Those mutations happen all the time.
Inhibition of chlorophyll synthesis may be caused by etiolation, mutant blocks, or streptomycin.
Mutations have altered the snake's receptor in such a way that, because the toxin cannot bind to the receptor, the acetylcholine function is undisturbed.
A hair-trigger situation has been created which could lead to an outbreak of war at any time.
Sickle-cell anaemia, caused by genes protect against malaria, is the most famous example.
Conclusion CACNA1H gene G773D mutation is able to increase calcium current and neuronal excitability.
A catastrophe potential function, which has the same form of swallowtail catastrophe, was obtained by dimensional normalization and diffeomorphism.
The results indicate that flashover in building fires is a phenomenon of swallowtail catastrophe.
Studies have detected no signs that the virus has mutated to a more virulent or lethal form.
More clues are coming from lab mice that have a genetic mutation that allows them to partially regrow severed digits.
Problems with adherence were a factor, but such strains mostly arose in patients taking drugs that were less effective than the combination therapies that later became available.
A study in 2006 found older men are more likely to father dwarves, due to an age-related genetic mutation in their sperm.
The genetic tests indicated that not much mutation had taken place before the virus had spread, suggesting short-term infection.
