Mathematical model of chromosome aberration

Ouchi, Noriyuki

Radiation dose, frequency of DNA strand breaks and frequency of chromosomal aberrations are commonly used for the measure of radiation effects. As we know, dose, DNA strand breaks and chromosomal aberrations are successive events, there are no common understandings for these relations. We are modeling chromosome using a kind of "toy-model", and extensively studied many dynamical features. Here, we will report on the physical properties of dynamics of chromosome, for example elastic movement, arising from computer simulation of our mathematical model.
