DNA is usually considered a word in its own right these days. Many people who know with reasonable clarity what a DNA test does would not be able to expand the phrase to Deoxyribonucleic Acid.

DNA fingerprinting
DNA Polymerase.
DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.
DNA, short for Deoxyribonucleic acid, has 19 letters if you expand it (not including the space).

The role of PCR primer design is to expand a few or a single copies of DNA across several orders of DNA. You basically make a lot of copies and use them for research. Attached are links to video webinars and primer design tools. They were made by IDT, or Integrated DNA technology. They are a company that leads the industry in this research.
