This is amazing, science is truly wonderful. PNA and DNA are really similar even the three hydrogen bonds and the Two hydrogen bonds in dna that holds guanine to cytosine and thymine to adenine respectively is just the same in the PNA structure. But there are two major difference I observed, PNA lack the five carbon ribose sugar and the negatively charged phosphate group. The absence of this two structure which are the two out of the three structure that make up a nucleotide makes PNA to be a partial nucleotide. It's specificity also makes it act like enzymes in that enzymes are specific in their actions.
