Abstract

Several species of a genus Cancer have a DNA that has a light buoyant density and that contains mainly deoxyadenylate and thymidylate. The presence of this polymer was demonstrated previously in testes and vas deferens. By a modified procedure for isolating DNA, the muscles, liver, and eggs of Cancer borealis are also shown to contain the deoxyadenylate-thymidylate-like polymer.
