The fact that each T4 virus within a population has the same sequence of genes but starts with a different gene at the 5' end suggests that the DNA is circularly permuted. This means that the genome can be circularized in different ways without changing the gene sequence. The other answer choices, such as two-fold rotational symmetry or linear palindromes, do not accurately describe this phenomenon.
