A 6 base site will occur on average once every 4096 (4x4x4x4x4x4) bp -
although this will vary depending on the GC/AT ratio in the DNA and in
the site you are interested in (& whether there are repeats) - but it is
a good place to start.
Therefore in 3x109 bp there will be 3x109/4096 individual fragments
