''Give me the calcium!'' Tulane virus takes over cellular …
"We also found that the calcium came from cellular storage in the endoplasmic reticulum and, to gain access to this source of calcium, Tulane virus seemed to use its protein NS1-2."
Calcium metal was not available in large scale until the beginning of the 20th century. Sometime prior to the autumn of 1803, the Englishman John Dalton was able to explain the results of some of his studies by assuming that matter is composed of atoms and that all samples of any given compound consist of the same coination of these atoms.
