Description
Transmission electron micrograph of unstained cryo-section of a sperm cell of the starfish Patiria miniata. Echinoderm sperm nuclei are unusual in that chromatin fibers are clearly seen, allowing their diameter to be accurately determined. Cryosections of frozen material are typically of low contrast and show defects such as knife marks and compression. In this image, the nucleus at upper right has partly torn away from the rest of the cell. Despite these defects, individual chromatin fibers are clearly visible.
