DNA carries the genetic blueprint in all cellular life.
A research technician is optimizing a protocol to extract genomic DNA from fresh strawberries (Fragaria\textit{Fragaria}Fragaria ×\times× ananassa\textit{ananassa}ananassa) for sequencing.
Describe the molecular structure of the double-stranded DNA polymer that is being isolated, and outline a step-by-step laboratory method to extract DNA from this tissue, explaining the biochemical purpose of each key step and reagent used.
