Studies are rapidly revealing the genetic changes in cells that cause cancer and spur its growth.
There were only five genetic changes in two of the viruses' eight genes.
Genetic changes in the virus could also be responsible.
That did not change, Dr. Forrest said, until molecular biologists showed smoking caused genetic changes in the lung.
None of those experiments involved deliberate genetic changes in the structure of the microbes — the basis of dual-use research.
The mutations are the first evidence that the radiation has caused genetic changes in living organisms.
Afterward, genetic changes in the cells signified that they were browning.
The ability of SARS coronavirus to jump to humans undoubtedly required genetic changes in the virus.
Genetic changes in the bacteria also may have contributed to the increased incidence.
In 1974, Dr. Brenner broke ground by using the chemical EMS, or ethyl methane sulphonate, to induce mutations, or genetic changes, in the genome of C. elegans.
The ability of the SARS coronavirus to jump from horseshoe bats to humans undoubtedly required genetic changes in the virus.
