difference in cell structure and getting gDNA

Question

What parts of the cell must be broken down in order to extract gDNA from an animal cell
versus a plant cell?

Answer 1

In both animal and plant cells, genomic DNA resides in the nucleus, which is surrounded by the nuclear membrane.  Additionally, both types of cells are bound by a cell membrane.  Plant cells, however, are enclosed by an additional cell wall composed of cellulose.  There are two barriers in animal cells (i.e., nuclear membrane, cell membrane) and three barriers in plant cells (i.e., nuclear membrane, cell membrane, cell wall) that must be broken in order to extract genomic DNA.
