- Primers used for the PCR of the present invention are roughly classified into (1) one kind of a primer having a specific sequence, and (2) a random primer containing a random sequence.
- the primers are partially identified on the genome. This is because it is desirable not to specifically anneal (complementary strand binding) to this region, but to non-specifically anneal to multiple regions on the genome.
- the present inventors have found that the base sequence of the 6-mer is important as an annealing region of the primer, so that the design is made so that a sequence with a high appearance frequency is included in the 6-mer or more. It is preferable to use the oligo DNA thus obtained as a primer.

In this way, the cycle in which the annealing temperature is lowered and the temperature is gradually increased, and then the loosening and elongation reactions are performed may be performed only for the first few times.
