Presentation transcript:

Origin‐fork purification. Origin‐fork purification. Total DNA from a 46−/49− phage infection (9 min post‐infection; left) and purified origin‐fork intermediates (right) were analysed by one‐ and two‐dimensional gel electrophoresis followed by Southern blotting with an ori(34) probe. The one‐dimensional gel position of the origin‐fork is indicated by an asterisk, and the 6.2‐ and 5.2‐kb linear fragments are indicated by closed and open arrowheads, respectively. 1D, one dimensional; 2D, two dimensional.
