with guanine.
If an unzipped segment of DNA is added as a template to a solution with the tPNA components, the nucelobase soldiers will automatically assume a formation on peptide strands that complements the DNA according to standard Watson - Crick pairing of adenine with thymine and cytosine
with guanine.
For DNA, adenine (A) matches up with thymine (T), and cytosine (C) matches up
with guanine (G).
New nucleotides — adenine, cytosine, guanine or thymine — are filled into the gaps on the other side of the backbone, pairing with their counterparts (adenine with thymine and cytosine
with guanine) and replicating the DNA to make a copy for both the old and the new cells.

with a guanine nucleotide on each of four corners, hence the name G - quadruplex.

With four different nucleotides comprising our genetic code (adenine,
guanine, cytosine, and thymine), the barcodes are long enough to be distinct from other stretches of DNA in the genome, and also allow for the generation of a seemingly limitless number of codes.
