Figure 3–27. Histograms of synchronized (1—5) and asynchronized cell cultures of Scenedesmus acutus (Nicolov et al.,1987). 1 — zero point; 2 — at the second hour; 3 — at the fourth hour; 4 — at the eight hour; 5 — at the tenth hour; 6 — asynchronized culture N — sample 1 ml.
In the literature there are data about single cases of asynchrony
observed during DNA-synthesis, in some phases of the mitosis and the
behaviour of nuclei. Such data are met in the papers of many investigators
