A short summary of this paper. USA Vol. In transcription of double-stranded DNA, self-com- strand replication. The isolated ori-RNA gave a simple finger- print after nucleolytic digestion and has a length of about 30 plementary base sequences and long runs of uridine at the end nucleotides.

The characterization of the oligonucleotides from of the RNA can terminate chain growth. For the primer in the the nuclease digest and the extension of the ori-RNA with DNA fd system, displacement of RNA polymerase by DNA binding polymerase I and subsequent restriction of the DNA gave its protein I at an opened hairpin structure may be another type exact localization in the fd genome, and its total sequence was of RNA chain termination.

This conversion can also be achieved in cell prepared to homogeneity as described. Other enzymes have extracts 1 and with purified proteins 2. In these systems and been described elsewhere 7 or were commercial products in vivo 3 , filamentous phage replication is inhibited by rif- Boehringer, Mannheim.

Incubation protein covers most of the single-stranded DNA, leaving a was at for 20 min.

Variations are mentioned in the text. The sample was de- fied as the in vivo origin of DNA replication for filamentous salted on a small Sephadex G column, freeze-dried, dissolved phages 9.

USA 75 0. In preparative ex- periments the fractions sedimenting with the template were saved for gel electrophoresis.

The plate was washed in methanol, dried, and autoradiographed. A transcript was formed in the presence of nucleoside triphosphates Fig. The synthesis decreased after 20 min but did not level off com- pletely.

Low concentration of nucleoside triphosphates reduced the RNA synthesis. Gel electrophoresis of ori-RNA. RNA synthesis was with was synthesized on the genome. The amount of RNA synthesized decreased as binding protein I. The length of the ori-RNA was calculated from its Downloaded by guest on June 7, the salt concentration increased. As will be discussed below, the mobility relative to ssDNA fragments of 20 and 42 nucleotides. Biochemistry: Geider et al. ELo 4. The bands of the ori-RNA Fig.

Both properties suggest that the RNA is isolated as a stable hybrid. Analysis of the ori-RNA. A dominant band was visualized in a size class of 30 nucleotides. The nine spots indicate a unique se- quence for the ori-RNA. Their composition was further in-. Table 1. The samples were 1 3'-OH oligonucleotide C-G Nearest neighbor The spots from the chromatogram Fig. U-G-G-OH hydrolysis. This spot localizes another end at position The numbers indicate the site of the largest of the four DNA fragments marked by asterisks in Fig.

The two restriction fragments at each cleavage site are indicated by capital letters.
