A certain purified DNA sample was cut with two restriction endonucleases $E 1$ and $E 2$ . The following results were obtained from agarose gel electrophoresis
Sample cut with $E 1$ alone: two bands of size $35 k b$ and $15 k b$
Sample cut with $E 2$ alone: two bands of size $40 k b$ and $10 k b$
Sample cut simultaneously with $E 1$ and $E 2$ : three bands of size $35 k b, 10 k b$ and $5 k b$
From these data, it can be inferred that the DNA has
