All the others disintegrate spontaneously with the release of energy by processes broadly designated as radioactive decay.
Using the ratio of the 14 C concentration found in an object to the amount of 14 C detected in the atmosphere, the amount of the isotope that has not yet decayed can be determined. So whichever marker showed up inside the bacteria would tell them what the viruses injected into it.
You can make it easier for us to review and, hopefully, publish your contribution by keeping a few points in mind. We welcome suggested improvements to any of our articles.
Carbon-14 contains six protons and eight neutrons. CC licensed content, Shared previously.
This is essential to understanding things like cellular transport, enzyme activity, protein structures, and disease mechanisms. Radioactive isotopes actinoid elements In actinoid element: How are isotopes of elements formed? Using this strategy they determined it was DNA that was being injected into the bacteria.
