Explanation:

Fresh biological samples have intact, unbroken DNA strands that form long, stringy structures when isolated. Processing (like heating, mechanical agitation, or chemical treatment) breaks DNA into small fragments, making it shredded. This breakdown happens because processing steps damage the DNA's long polymer chains.

Answer:

A fresh sample usually has DNA that is long and stringy, whereas a processed sample will have DNA that is shredded
This difference is likely due to: Processing steps (mechanical/chemical/thermal stress) break the long DNA polymer chains into small fragments, while fresh samples have undamaged, intact DNA strands.
