Abstract
1.
1. A deoxyribonucleoprotein, found in extracts of Escherichia coli B(H), has been investigated with respect to its role in DNA and RNA synthesis.
2.
2. A deoxyribonucleoprotein in ribosome-free cell extract could be separated from the other cellular components either with gel filtration or zone electrophoresis.
3.
3. The isolated deoxyribonucleoprotein was composed of roughly 80% of DNA a and 20% of protein.
4.
4. Association of DNA polymerase (deoxynucleosidetriphosphate: DNA deoxynucleotidyltransferase, EC 2.7.7.7) and RNA polymerase (nucleosidetriphosphate: RNA nucleotidyltransferase (DNA dependent), EC 2.7.7.6) with this deoxyribonucleoprotein has been demonstrated.
5.
5. DNA polymerase and RNA polymerase, purified from E. coli extract, had an ability to form a complex with DNA.
