Paper Abstract

The S11 and S14 scattering matrix elements were measured for light scattered from single dinoflagellates and single irregularly-shaped, alumina particles suspended in a transparent gel. The S14 matrix element indicates the degree of circularly-polarized light induced on incident unpolarized light. The S4 signal from the dinoflagellates was found to be significantly larger than that measured for the alumina particles. The nucleus of the dinofiagellate investigated, Prorocentrum micans, contains about 50 structurally complex, chromosomes with a helical structure. This work provides evidence in support of the hypothesis that the observed S14 signal produced by the light scattering from P. micans is due to the helical nature of their chromosomes.
