What does it mean when dna is openly floating around the cytosol

Most, maybe all, bacteria have their genome DNA tethered to their cell membranes, so it is in the cytoplasm but its not really floating around. Plasmids in bacteria however are free floating. This is why it's so easy to isolate plasmids from bacteria with centrifugation after lysing.

The nucleus is damaged.

Explanation:

The nucleus is supposed to keep genetic material (DNA) housed within its membrane-bound structure, but in this cell, the genetic material is openly floating around the cell's cytosol.
