| Abstract |
The processing of newly replicated concatameric T5 DNA into both single stranded DNA changed of unit length and single-stranded fragments of sizes comparable to those found in mature T5 virion DNA occurs in the absence of late T5 protein synthesis. The formation of unit-length, single-stranded DNA chains does not require the early T5 gene D15 nuclease: however, the subsequent formation of the single-stranded fragments does require that the D15 nuclease be functional. A reexamination of the properties of the purified D15 nuclease under a variety of conditions showed that, in addition to functioning as a 5' leads to 3' exonuclease, the enzyme can also introduce endonucleolytic scissions into mature T5 DNA in a reaction that requires duplex T5 DNA and preexisting, single-stranded interruptions. |

Figs. 7,9. D15 endonuclease activity was witnessed as it digested native T5 duplex DNA. The different bands produced in the gel electrophoresis proves that D15 (also referred to as flap endonuclease) has nuclease activity which cleaves the T5 genome. |
