Metrizamide density gradients of sea urchin chromatin: fractions rich and poor in nascent DNA.

A crude, lightly sheared chromatin preparation obtained from a mixture of [methyl-3H] thymidine pulse and [2-14C] thymidine long-labeled sea urchin embryos (swimming blastulae), was centrifuged in metrizamide to form an isopycnic gradient. The buoyant density of the 3H pulse labeled chromatin was sl...
