DNA extracted from peas

Looks like the moon on a dark night? Well yeah, but actually, it’s not. It’s a picture of green peas DNA  that I took during our Cell Biology class (third year first semester). It was viewed under a Compound Light Microscope’s High Power Objective with a magnification of 1,250x. This was extracted by my classmates Poll and Jencel. I and Chai was not able to extract a whole DNA but damaged ones instead.
