DNase I digestion (trimming) of head-associated DNA. Modified heads (MH fraction of a sucrose gradient; 43.6 μg DNA/ml) were diluted by a factor of 0.36 and subjected to digestion with either 75 or 200 μg/ml DNase I, as indicated above bracketed lanes. Then, the DNase was inhibited, the DNA was expelled from heads and the DNA was subjected to gel electrophoresis (Materials and Methods) in the following amounts: 320, 192, 48 and 16 ng. The length standards are in lanes marked as they are in Figure 4.
