Yes, it's true for all living organisms.
All animals/plants are made up of cells, and DNA contains the info/data for these cells to develop properly.
If you think about evolution more broadly, all living organisms evolved from single-cell organisms, so it would make sense that DNA is an important part of all of their growth/development.
point B this is a topographic map the lines indicate the elevation of the area and B is at the lowest elevation which would be where the water would gather
