what strategies do i need to use to know yenetic material

I think that the estrateyis to know about DNA is:



have a microscope, have an expert in sciense and have an animal or a plant to the experiment.



I needa very good microscope to look insidethe cells because the cells are very small andthe DNA is inside the cells. I need an expert in biology becausethey know about cells very much.



I can use an animal or plant to studi their DNA. I can not use rocks or earth because they dont have DNA only the living things
