Summary
The DNA content was studied histographically in the nuclei of the cells of certain mitorically dividing tissues (spermatogonium, fibroblasts of albino mice, liver cells and those of the pancreas in young albino rats). The authors came to a conclusion, that the process of DNA reduplication is nonuniform. Each subsequent stage of the DNA synthesis is more intense than the preceeding one; the rate of synthesis increases during the second half of the process, reaching the maximum near the end of reduplication.
