Question

Is there DNA in your food? how do you know?

Answer 1

yes, of course there is. If you are eating meat, its right in the cells. Just because the cells are dead, doesnt mean the DNA disappeared. It would take a while for it to disappear. If you are eating vegetables its there. Its in bread too because this is made from wheat, a plant. However, if you are eating rocks you would not find DNA. 

Answer 2

there isn't until u eat it because ur saliva gets into ur food as u put ur fork or spoon in it so until u put a fork that u put into ur mouth then there would be DNA.
