Weigh the strawberry and record its total weight. Cut off a small piece of the strawberry, weigh the piece, and record the piece's weight. Crush the weighed piece and treat it with a substrate that will suspend particles with negative charges. Filter the materials suspended in the substrate to isolate the strands of DNA. Use imaging tools to find the exact mass of the DNA. Divide that mass by the mass of the strawberry piece and multiply by 100% to get the percentage of the strawberry's mass that is DNA.

It is possible to determine the percentage of a strawberry's DNA mass by ultracentrifugation.

Ultracentrifugation is a technique used in molecular biology laboratories to separate different cellular components.

In ultracentrifugation, cellular components are separated according to their densities.

During ultracentrifugation, the denser molecules and/or cellular components settle down faster.

In conclusion, it is possible to determine the percentage of a strawberry's DNA mass by ultracentrifugation.
