The enzyme responsible for the breakdown of the rapidly labelled ribonucleic acid ( RNA ) in the HeLa cell nucleus has the properties of a polynucleotide phosphorylase. This enzyme acts preferentially on the rapidly labelled RNA and appears to degrade it to nucleoside-5' diphosphates. Both the rapidly labelled RNA and the enzyme which degrades it are apparently attached to the chromosome.

Molecular Weights

1. Conditions have been established for the estimation of molecular weights of proteins by analytical gel filtration and sucrose-density-gradient centrifugation in 2.5m-potassium chloride–1m-sodium chloride; Halobacterium cutirubrum polynucleotide phosphorylase, DNA-dependent RNA polymerase and RNA-dependent RNA polymerase have been studied by these methods. 2. The RNA-dependent polymerase has also been studied by density-gradient centrifugation in the absence of salt. 3. All three proteins are of unusually low molecular weight compared with similar enzymes from non-halophilic bacteria.
