Fractal behavior of length change in human mitotic chromosome

Abstract

Sixty-six cells were examined for chromosome length change, with half of them (33) in the early-metaphase and the other half in the pre-metaphase. The 22 couples of chromosomes (excluding sex chromosomes) in each cell were analyzed. The differences of chromosome length between the two phases were demonstrated and the correlation dimension of each chromosome was calculated. It was suggested that the mitosis of human chromosome possessed the feature of chaotic decrease. This offers a new approach to the research of the dynamic process of the mitosis.
