✦ Synopsis

The ribosomal RNA genes from the sea urchin Lytechinus variegatus have been studied with the electron microsocope using the technique of denaturation mapping. A repeating pattern of denatured regions was found with an average repeat length of 3.87 +/- 0.24 mum. This corresponds to a DNA sequence of approximately 12,000 base pairs with a molecular weight of 8 X 10(6) daltons.
