Answer:

Step-by-step explanation:
The process of releasing DNA from the nucleus of cells is called lysis. Lysis is one of the three basic steps involved in DNA extraction:
Lysis: Breaking open the nucleus and cell to release DNA
Precipitation
Purification
Lysis involves mechanical disruption and uses enzymes and detergents like Proteinase K to dissolve the cellular proteins and free DNA. For example, in the case of bacterial cells, a solution of detergent and salt (such as SDS) can be used to disrupt the cell membrane and release the DNA.
DNA extraction is the first step for almost every method of DNA analysis.
