No - except in pregnancy (where you keep and multiply half of it).
Note ... all foreign DNA is either digested or destroyed.
so your dna can replicate and keep your body functioning properly
yeah their could be
Chromosomes are made up of DNA in living organisms. In humans, the DNA is located in the nucleus of every cell in your body. The chromosomes are the map to the human body and contains instructions for each cell to follow, building proteins to keep the body functioning,
we have DNA to make proteins.
Well most of the body contains DNA but nobody knows really how but DNA you have in your body.
DNA is necessary to construct proteins for the body.
Usually the total body does not burn. If there are bones, which usaully are, the DNA can be obtained from the bone. Or a tooth or other body part that comtains DNA.
Yes eyes do in fact have DNA in them evry cell of your body has DNA in it
They are the same. The DNA is the same everywhere in the body.
The answer is NO. You can modify a particular part of the DNA by mutation but an entirely different DNA cannot be incorporated into another DNA simply because DNA is present in each nucleated cell of the body and as there are millions and millions of such cells, its not possible to do it. :)
A single cell in you body can hold 2 m DNA.
Any secretion of you body that may contain cells of your body can be used to extract DNA.
