The DNA is present inside the cell and the cell is encapsulated by the plasma membrane. In, eukaryotes, the DNA is further localized in the nucleus and that is also surrounded my nuclear membrane. If one would not rupture the membranes, the DNA will not come in the solution and could not be precipitated.
Simply to reach on DNA and extract the gene of interest.
When the soap is added, the enzymes in the detergent will break down the lipids in the cell membrane like soap would do to a greasy pan. Also, in the meat tenderizer portion of the lab, the enzymes in the tenderizer will break down the proteins.
The nuclear membrane fades during the prophase of mitosis or meiosis. This is the stage when the membrane begins to break down and disappear, allowing the chromosomes to become more condensed and accessible for cell division.

During Anaphase.

In a strawberry to extract the DNA it is required to break down the cell membrane (both the membrane protecting the cell as well as the membrane protecting the nucleus) and pectinase and cellulase in strawberries are enzymes that are break down these membrane...at least in a strawberry.

The nuclear membrane breaks down during prophase, while the Deoxyribonucleic Acid (DNA) The nuclear membrane must break down to allow the chromosomes to be pulled apart and away from the area of the former nucleus towards the pole where the daughter cell will be formed. If the nuclear membrane did not break down the spindle fibers would not be able to reach the chromosomes and they would not be moved towards opposite poles of the cell.

ATPase Is an enzyme that works in and around the membrane to break down ATP (Energy Made By The Mitochondria) into ADP
Both prokaryotic and eukaryotic organisms break down molecules to produce energy.
glucose, iodine.. but not starch... its too big so i has to break down into glucose before it can cross the membrane
Bile is used to break down lipase during digestion.
