The present invention provides methods for amplifying a complete genome or transcriptome. The genome or transcriptome is prepared as a set of target nucleic acids and mixed with a first primer. The first primer comprises a target-binding region having a first random sequence of about 6 to about 9 nucleotides and a tag sequence that contains one or more non-natural nucleotides. The first primer is annealed to the target nucleic acids and extended by polymerase to produce a first duplex nucleic acid. The target nucleic acid is removed from the first nucleic acid. A second primer is annealed to the first nucleic acid having a second random sequence of about 6 to about 9 nucleotides and a tag sequence that contains one or more non-natural nucleotides. The second primer is extended by polymerase to produce a second duplex nucleic acid. The second nucleic acid contains a tag sequence on one terminus and a complement of the tag sequence on the other. The first nucleic acid is removed from the second nucleic acid. A third primer is annealed to the second nucleic acid having the same sequence as the tag sequence or a portion thereof and at least one of the non-natural nucleotides of the tag sequence. The third primer is extended by polymerase to produce a third duplex nucleic acid. The second nucleic acid is removed from the third nucleic acid. The third primer is annealed to the second nucleic acid and the third nucleic acid. The third primer is extended by polymerase. Repeating these last three steps thereby results in amplification of the genome or transcriptome.
